It's really not worth panicking and selling. Recently, I was convinced of this, when during the downrange tokens from my portfolio, namely NEAR ATOM, grew well during the fall of BTC. Near even updated ATH during the downtrend. That's why I remain a holder and I feel great
So, what if those coins that you have mentioned never really did well in the market, would you still panic? You have to be prepared for it, because such things do happen. What if Bitcoin starts to go up all of a sudden and those coins starts to lose their value, since it seems like they don’t correlate with Bitcoin in price?
But, it is good that you were able to find the right coins at this time and invested in them. But as an investor, loss is something that you can’t really escape from. It happens to everyone once in a while, but if you know how manage your risks, and how to plan your investment , then you wouldn’t make the worst mistake.
