Being a participant in the cryptographic market is a part-time job, so I think long-term investment is a smart decision. I will choose the potential e-currency and buy them at low prices. I will wait when their price is high then I will sell for profit. I have good income when following this strategy!
To ask: How long is the long term investment hodl? Is it just for hodling sake ? I think we need to ask ourself this. Asides bitcoin and ethereum I dont preach Hodl for other altcoin, it could be dangerous to hodl for too long time.
