do you think crypto could become a mainstream currency?

personally i believein a few years if it keeps doing as well as it is, it is very possible

For the video i watch a few moments ago, no. It had it's time but things could change.

Probably in a few years, makes sense that it becomes the main currency.

Not in the currency form but maybe smart contracts for banks and stuff is going to be way to go.

Crypto is well on its way to becoming a mainstream currency. A lot of businesses currently support crypto (not altcoins), but I can order a VPS and a pizza with crypto so I think yeah.

I think it already is mainstream

For my it's now in mainstream, crypto is really popular
