Invest Long term
Why invest long term? Because that's where all the profit is. If you day trade you not only loose money because of the fact you can't predict when a good time to buy/sell is, but you also loose money in fees every single time you trade.
The best strategy in my opinion is to buy low, hold long term, then sell when your coin is EXTREMELY high. I'm talking buying at a couple cents, and selling at hundreds of dollars. That's the kind of ROI I want.
Also, quick side note: A lot of alt coins are down in price today, so it's a good time to pick some up. ;)
(Please excuse my MASSIVE bedhead lol)
