I can convert btc to fiat so I think bitcoin and other cryptocurrencies are redeemable. I usually use TRX to buy game items and there is no problem with it. Even El Salvador start to adopt bitcoin. I get a lot of profit from holding bitcoin and then I bought a car using that profit. I can convert my BTC to Gold if I want. But of course for me it will not be a profitable investment anymore. I bought bitcoin and I am not pretend it as a gambling, I did observation, calculation and etc before investing.
