Because I'm sure waves will be a very profitable coin, it is evident that they continue to develop technology so that prices can be stable and up.

There is a desktop wallet for waves. Though it syncs with the internet.
They still have not got proper way to redeem your tokens through private keys. (Waves is shit)

When is better to buy crypto, on pre sale or on ICO? When you buy on presale, you can get good bonuses, however when you buy on ICO you have a better gurantee not to be scammed.

I still hold 4 coins and I think that this is the best option at the moment. They are Ethereum, NEO, Ripple and Cardano.

I strongly believe that blockchain technology and cryptocurrencies are the future. This is why I believe the price of Bitcoin will increase this year. This is what I believe, but I can never know.

I doubt that cryptocurrencies will ever replace fiat, at least not cryptocurrencies as we know it -- ie. the permissionless and independent of government type.

Whether some sort of government "cryptocurrencies" will appear is a question of its own, although I doubt the viability of this concept. Either way, in my opinion cryptocurrencies are going to play a large role as a means of payment, regardless of whether it will complement or replace traditional money.
