I think lately markets are having a difficult time to recover. We can also see this in other markets like stocks and forex as well. The so called crashes happens around every 10-12 years. In crypto I think it may happen around every 3 years. 3 years of growth then a correction which would then take around 1-2 years before the bears are exhausted. But right now is different because regulations and big money are coming round the block. So just watchout and be vigilant.
