FAQ for Beginners

What is Bitcoin?

Bitcoin is scarce, decentralized, and global digital money that cannot be censored.

Quick Advice

  • Do not respond to strangers messaging you with investment advice or offers and read how to avoid being scammed from the posts below.
  • Do not invest in Bitcoin until you do basic research, paid off all high interest debt, and have a emergency savings account of a stable fiat currency.
  • If investing do not expect to get rich quickly. You should expect to wait at least 1-2 years before taking profits. Bitcoin is currently very volatile. In the interim spend and replace Bitcoin because its a useful currency.
  • Beginners should avoid all mining and day trading until at least very familiar with Bitcoin. Mining is very professional(You cannot efficiently mine with your computer and need to buy special ASIC machines) and most people lose money day trading.
  • Never store your Bitcoins on an exchange or web wallet. Buy your bitcoins and withdraw it to your personal wallet where you actually own them instead of IOUs. Services like Robinhood, Revoult, and Etoro should be avoided because you cannot withdraw or use Bitcoin.
  • Make sure you make a backup of your wallet(software holding keys to your BTC) and preferably keep it offline and physical and private. Typically 12 to 24 words you write down on paper or metal.
  • Beginners should avoid altcoins, tokens, and ICOs at least initially until they learn about Bitcoin. Most of these are scams and you should be familiar with the basics first. Bitcoin is referred to as BTC or XBT.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic
