sell at $100 in 2050 Grin Grin Grin Grin Cool
Cryptocurrencies won't even exist in 2050.. blockchain is just bad technology. It worked for a couple of years but it's over now. Bitcoin is falling to 0, everything is falling.. Dubaicoin is one of the least useful altcoins so it will die for sure.
Stop wording your opinion as if it is fact, you don't know that, you can't predict the future. Anything is possible, but the blockchain will always have a use.
