Personally, I don't trade no more, its been very last since i traded last, I was a short term trader then, but to be really successful, the coin you are trading have to have alot of liquidity, If not, then its all a waste of time and effort, long term trades are more suitable with coins with less liquidity but liquidity still have to be enough to be successful too, in all, from my personal experience, both trading strategies are very good, what's most important is that you are in one that works really well for you.
