I think the crypto market will continue this way as long as there are no regulations that truly control it throughout the world. Maybe it should be the price of coins now. If 2017 is just a pump, some even try to review the news. We can't also assume that with high prices the market will become stable.
If anyone assumes that with high prices the market will stabilize, then that is very wrong, because in 2017 all coins have been at the highest price, but the market does not look stable, and that is proven in 2018, where all coins have decreased in price which is so severe, that many of the investors suffer losses.
When the market is open 24/7 and if it is decentralized then there is no chance for a market to stabilize. Cryptocurrencies are volatile even when it is just getting started and there is no chance for us to lessen the volatility. We should just adjust and adapt with the market situation and take it as our advantage to prosper in the world of cryptocurrency.
