ivebeen reading an artcile about mining and found this info : 80% OF AVAILABLE BITCOINS ALREADY MINED.
whats does this means ?
That is the amount of bitcoin left to mined by 20%. if it has reached 100%. Whether the change from POW to POS, or could be a miner only to confirm the transaction only, so the miner can only get a fee from the transaction itself. We will see later.
is it too late ot get in ?
It's never too late if you have a tool for mining.
because here forum altcoins. Of course, the equipment used GPU to mine. Did you mean using GPU? It can not be done because Network hashrate and Difficulty are high. unless you mine altcoin then converts it to Bitcoin.
