People who suggest not to invest in cryptocurrency are simply impatient or lazy enough to do a proper research. They have already failed in earning quick and easy and now are angry on the whole World. Once I've bought Waves tokens when Sasha Ivanov hyped them with Vostok airdrop. During 2 years, Waves were on the bottom from ATH. This altcoin in my wallet was a reminder that I must choose wise where to invest. Many times I have thoughts to sell them. Last week their price doubled and I happily sold all my Waves. They are my best lesson to wait, be calm and continue to invest.
