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.
Congratulations, good job on being able to make a strategy on how you will invest as early as your what your rank is in this forum. Although I do not know if you already have a background on investing into cryptos or any other investments before joining here, I really find it amazing that you really have studied a lot about cryptos which has then paid off because you now are able to device a plan on how to invest.
Just a hint though, be careful with this strategy of yours because sooner or later it will fail if you do the exact same thing with every coin/token that you get your eyes on. It is better to be prepared always and understand that not every coin is alike and that cryptos can be predictable today but a completely different story tomorrow and become very unpredictable. But don't worry, you will eventually get the hang of this. And when that time comes, then you will know what to do easily when an opportunity comes. It will somehow be natural to you and be just like an instinct.
This skill can only be learned by experience. You might see a lot of advises and more, but at the end of the day, none of them will be the one accountable for your loss or gains. So be sure to take notes in every experience you get through so you can be able to create you own decisions and be more confident with them every time. hope this helps.
