It feels like 2018 is one of the hardest year for all the people who are involved in cryptocurrency, because all them people who I know personally are involved in every aspect, are constantly losing their money.
I think those ones that invested in crypto after March, will get their profits. Investing in Ethereum is the right decision as it is the best altcoin with the huge potential.
After march, yeah the must have done something amazing. First achievement bag in their account is, they have trusted bitcoin or altcoin for their investment source. Secondly, they have selected good strategies that are working fine for them till now. Buyers in March must have good investment profit even if they sell bitcoin right now. But I will advise them to keep their coins for long time.
