They are all selling at a very good price now. The best time to buy is now
Every time it is good to invest in crypto but it depends on the level of crypto knowledge. However, people have a different purpose and understand in the crypto investment and with the current movement of the bitcoin market (it clinched $10K it dump back) i won't be surprised if some investors choose to sell their holding in other to buyback when the market dump cause the market seems to repeat it and was what makes some people believed the whales are behind it all.
This is something interesting about trading what has happened before repeats itself. Thats why i am excited about the next pushup its better to start investing now
