I am mostly a hodler no matter the market going down or up. But sometimes I get the advice to take some profits.
Example: my investment of 300 euro becomes 500 euro. Is it better to take out my initial investment or only take the profit ? And reinvest that profit ?
How do you guys do this ?
I just feel like i'm missing potential profits by not selling and seeing my potential profits go up and down.
Taking a low profit is better than ignoring the existing profit. Because with these profits, you can invest in the next opportunity. If with Euro 300 you can get 0.163 ETH, then Euro 500 can earn 0.272 ETH. So in my opinion, taking advantage of any amount is the best solution than ignoring it.
Profit is profit. No matter how big or small it is, the aim is not to lose an amount of what you have invested or bet. This is where greed plays a role to some people. There are instances wherein investors are aiming for a bigger profit but since this market is unpredictable, things could change in an instant. This is why taking the profit would be best. There are also instances wherein profit gets bigger but that would be a gamble. Setting a mindset that a small profit would be enough, ATLEAST, is far from risking it all and ending up losing for that day.
It is very common that someone that is expecting huge profits out of an investment that they made decides to not sell their coins when they are making a small profit, and this can be a huge mistake, because as you say making profits, any kind of profits no matter how small, is way better than to take losses, maybe having small profits out of each trade is not going to make you a millionaire immediately but if you give it enough time and you are able to remain constant while keeping your losses as small as possible then it is just a matter of time before that happens.
