Other BTC, are you holding any other crypto?
Well well, definitely. Take a look here
If you spent $1000 to buy 1 BTC, after 5 years, you still hold 1 BTC. the only things has changed is the Bitcoin Value itself.
But, if you spent $1000, buy BTC, convert to ETH, after 5 years. Perhaps the ETH you sold might have more than 1 BTC compare to holding it. The thing that has changes is the quantity of BTC
I am currently holding 20 crypto+ Mainly DNT, Coss, Neblio are the big holding
