Seems like some people are acting like they know everything about trading. If you truly want to remove emotions you MUST do the following.
1. Setup and entry plan -> Let's say we want to get 1BTC for $5000, then we will wait until it is that price, or we can say that we just buy 1BTC at the current market price (whatever that might be at that time)
2. How much do you want to gain? Since this is an example let's assume we want to get 10%, and taking back the example that we buy 1BTC for $5000, we would calculate that we will hit a 10% gain at $5500.
3. CASH OUT THAT $5500 no matter what. This was your plan since step 1, so why not stick to the plan.
See here that I never mentioned I want $500, or I think Bitcoin will go up or down.
It is simple, just enter and exit when you have realized the gain that you wanted. (Same way goes for if the price goes lower after you buy, set up a max% that you want to lose or just HODL. However, investing is always a risk you are taking, so never invest money you cannot lose.)
This is just my strategy and has been working
Hope it helps others
