I study the project and choose the one I like most (promising) in order to invest. Last week I bought PundiX
Good fo you mate, I think these days were all at cheaper value of coins and this is a great opportunity for all of us now. PundiX and other crypto has more potential to gain high price in the future so grab yours now, wait until such time it increases a profitable value. Never give up on cheap coins, and instead of being panic always stay calm, focus on your goals.
