Hey
I once came across a time when I was unsure where the market is going to take us , thus I brought at a very high price , unfortunately the price came down as quickly as it climbed up.
The reason I believe I haven't lost even a single penny is because
I believe you cannot loose when you don't encash.Therefore I still believe holding for the long term can actually help you .
After the retreats in Altcoin prices, the old fashion came up again. If you don't sell out, you won't lose. Good and interesting point but I remember last pre-bull period for altcoins. All alts getting melt like an ice cube. And people has started to worried. Then some of them had to sold their coins. Because cash needed.
If you don't need cash in short term, it is good suggest. But if you may need cash, I don't think it is a good idea.
