Cryptocurrencies in comparison with Fiat is more volatile but very rewarding. The problem I faced during this cryptocurrency investment journey, to chose and decide which is legit trading platform or trading company, starting from 2016 to late 2018, there was epidemic of these scam trading platforms, I was bit taken back as I lost few Bits into cryptocurrency. I think before investing, there should be community voted and reviewed platform instrument where we can build our trust.
