Sooner or later, everything will change, because the blockchain is developing very quickly and many technologies enter our lives.
That might be true, but we are not so close to blockchain getting into mainstream, we still have to see real application of blockchain based projects in everyday life.Those crypto based debit cards came closest to the real use, but we can see new projects on the daily basis and in a few years we might see real mainstream application.
Well you already have mainstream applications like apps for buying crpyto, though they are like a bridge between crypto and fiat. You have tippin.me and you can use it to tip people on Twitter for their good tweets.
