I cant understand why BTCZ and now BTG both equilhash based coins whats the difference between them both this is confusing for a small miner
Well, Bitcoin Gold is a work in progress to convert the bitcoin coin base to the equihash algorithm. It holds no additional features and no privacy updates. It has a large crowd of people who want to mine bitcoin gold with their gpu instead of asic. I hope Bitcoin Gold works out because it will bring a beautiful addition to equihash which was developed by Alex Biryukov and Dmitry Khovratovich, cryptographers at the University of Luxembourg. It is ASIC resistant.
BitcoinZ is a fork of Zcash which has a bitcoin related heritage, BitcoinZ supports t1, t3 multisig and z_address wallets. -t1 is a regular wallet with no intended privacy features. t3 is a multi signature (more than 2 people have to agree on the transaction for it to transact) wallet which you can use or test out with the MyBitcoinZ application. z_address is a zero knowledge transaction meaning that it can “shield” or hide funds from view and giving privacy of transactions and balance held. None of these are new blockchain technologies but the BitcoinZ Community is aiming towards new comers or people interested in crypto currencies. I hope that everyone using BitcoinZ feels that they can easily access their coins and feels
Confident in what BitcoinZ stands for; a decentralized crypto currency with no central entity. It’s important to have convenient public access for everything related to BitcoinZ.
I know a lot of people 8000+ wallet installations are waiting for a more convenient exchange that has trust. One simple problem that is rather new and difficult for a community driven crypto currency is that a lot of coins or ERC20 ethereum tokens are doing ICO or “initial coin offerings” which raises up to millions of dollars and therefor paying large sums of money to exchanges to list their coin or token. I’ve personally reached out to almost all exchanges and they all requested 4-15BTC for listing. The listing should be free because they earn money from the fees for each exchange. I assume since BitcoinZ is growing so quickly that an exchange will pick it up soon.
