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.
its always been that way since the beginning of BTC, the first time i experienced it was when btc spikes up to $1200 back 2014 and started crashing again to $250. that's a huge backward leap but this wasn't the first. it also hop high last 2017. its amazing how it always happen so you can expect that it will happen once again. its just a matter of time that. it could happen next year or maybe even in the next 3 more years who knows.
