I'm sure the bear market has taught most investors to be cautious. Given the huge losses suffered by those who invested in cryptocurrency at the end of 2017 and the beginning of 2018, they will act differently, diversify their risks, not put all their eggs in one basket, learn the rules of money management. Given the resumption of the uptrend in the cryptocurrency market, those who continue to hold the depreciated tokens can expect to restore their fair price.
Investors indeed need to be cautious and I think most of them have learnt it the hard way, but when it comes to cryptos maybe putting your eggs in one basket makes sense. Im advocating investing only in bitcoins as year after year bitcoin has given stellar returns to its investors, in comparison to other alts. The biggest lesson I have learnt and this will be repeated by all, is that we should learn to hodl our coins irrespective of the short term fluctuations.
