if there is only one left it will be BITCOIN

Bitcoin will surely become the global benchmark for virtual currency

this will become as stable as a national currency such as the dollar, the euro, the pesos or others....

it will become much less volatile because by then the world bank will have regulated it and

regulated

so when and how much are the only questions you need to elucidate

regarding the other cryptos which are far too numerous today, there should only be 2 or 3 left per country like a national currency, it's up to you to find which ones and bet on them

to conclude the time for big profits in crypto is numbered

enjoy

long life to you
