I hope the crypto currencies will become mass adopted and will be ready for every day usage. If not, it is going to be pretty sad, that the market is not developing and it is not going to survive if we won't see more working products.
I am also thinking of more adoptions could happen in cryptocurrency after 3 years. Although with so many hindrances in crypto and many things can happen I think it will survive. Their is growth in crypto and more users adopts crypto.
