The next time you pay for something, always encourage them to accept crypto.
This is how your transfer the market cap from fiat to blockchain and this is how you realize true gain, your 10 coins valued at let's say 100$ can go to the moon if more people would switch to crypto.
I believe the two lines above are a bit inconsistent. For people to help cryptos become massively adopted asking people to accept coins as payment is sort of a good idea, but, like you said, they should not convert it into fiat. If they don't then they should not really care how much in fiat do they have in each moment of time. 1 btc is always 1 btc regardless to whether it is worth $600 or $6k, right? Only with such an attitude cryptos can really replace the fiat. You, on the other hand, say that making people adopt the coins will help them to moon (and you give a sum in usd to prove your point), so it's still about converting stuff to fiat eventually.
