Yes, at the end of 2017 there was a huge HYIP on cryptocurrencies and prices soared very high, so it is not surprising that this year there was a recession. It is not known how long this will continue, but if we want to be successful in this industry, then we must remain here and believe until the end in crypto-currencies.
It was something like that, but I could not call 2018 the year of correction. The correction simply cannot last for many months. It was a period of stagnation as perssimist say, and the optimists will call it the stabilization.
