I know it's advisable to buy low and sell your coin at a higher price. What I don't understand is that when you sell high, do you suppose to buy so that your profit will not depreciate when the price is going low? I need an expert to clarify me, Thanks.
We have different ways on what to do with the profits we jave gained in trading. From my personal experience, my profits will be use to buy another altcoins at the dip. Or I will add some bitcoin to my wallet from the profits I got from trading. Not everytime I do that, I still spend some of it by buying some few things I need for my personal needs.
If I am trading a particular coin that I trust to always have volatility, what I do after getting the profit is to join the profit to the capital would have increased my investment coin, and then use it to trade the same coin again, when I see the price dip again, and this is what I have been doing in my Bitcoin trading that has made the BTC I have now grow in both quantity and also grow in value too.
It is not bad to use the profit to buy altcoins, but I can only use it to buy them for long term investment and not trading, because not all the altcoins are really good for trading as they have very low volatility.
