This is the Strategy I was following in crypto. This is the example.
buy coin 300A @1.00 = 300
Sell 150 @2.00 (Now you covered your initial investment(Excluding fee))
Sell 50 @3.00 = 150
Sell 50 @4.00 = 200
Keep remaining 50 for long term( If market is crashing you have to sell this proton immediately).
But this method can't apply if the market crash before it reaching to 2x. I would like to know the approaches/Strategies you are following and drawbacks of this method.
There isn't really always a fixed method, but if you want to avoid the latter circumstance, a good strategy would be to choose only ICOs that actually have potential based on the driving team and the product they are pushing. When you see a lot of ICOs everyday, it's not that hard to learn which actually has some use and which are just trying to earn.
