You are right about that, but do you really know when it actually the end of the blood, I think no. So why believing it's best time to buy, there is no actual time to buy same as every time is good to buy, what if you need it you have to buy it.
If you have some extra money then of course you can invest it in cryptocurrency. But so far I would not be in a hurry to invest in digital money. In any case you should not actively buy little-known tokens. They may still fall in price.
