Accept that coins can go to zero, and even good coins can lose up to 80% of their value (especially against BTC). There are many coins that didn’t make it to 2018 that were once highly valued and popular. Meanwhile, even some giants of today like ETH and XRP have seen their value in BTC prices drop to depressing levels. You should prepare for this mentally and have a strategy that factors this in. If you buy the dip in ETH from .15 down, .08 may look like an excellent price, but you have to be ready for .02. ETH holders who didn’t prepare for this had a depressing June 2017 – December 2017. Heed my warning, that new coin doesn’t have to moon twice, it can go to literal zero, and even those that will moon again… they can have long seasons of stagnation in between (where they lose value against BTC for months on end). See the Crypto Graveyard and please look at the historic charts of major alts like XRP (the gap between moons is real and some coins really don’t make it).
Trading strategies are there to provide objectives for traders to earn more with lesser capital; just like how a successful business should operate. There are a lot of trading strategies that are being written all over the internet today, but what we’ve noticed is that most of these so-called “strategies” are just plain common sense; something that is hard to come by nowadays.
