This period do not encourage trading or investment but at the same time when price is down is good opportunity to buy cheap and when its explode you will gain it. Nothing is lost in bitcoin, those holding for long now are the great benefactors but if you buy this period is more safer.
If I have money now, I would buy half of bitcoin because in next three months it will double the current price. This is real because it always occur this way after 5 years remember in 2011 and 2017 from the market charts and caps. And this year will break more even.
But in practice, we don't know which price range is cheap. Sometimes we think the price is still too high, but tomorrow morning it has gone up to 10%. Or other times we think prices have gotten cheap but still drop for a whole week.
Investing in bitcoins is not as easy as it seems. When you see that the market is getting worse, you will be confused, whether to hold it or sell it, when the market improves, you also doubt whether to sell it now or tomorrow? Especially if you store in large quantities, it will make it difficult for you to sleep
I've tried it before, and it bad ended. Train you to understand analysis and news about the assets you hold. Also use cold money so you don't rush to sell your bitcoins at the wrong time because you need money. That must be bad
