This ain't a buying opportunity. You will be lucky if you make 2x out of that. There are altcoins out there that make 2x every week. Steem for example.

Other altcoins make 100x jumps and yet people still invest in Bitcoin. Imagine you buy a Bitcoin worth 10k for $1 (just an example) and it jumps to 20k you now have $2.

Imagine you buy "Lesbiancoin" for $1 when it is worth a cent. After 1 week lesbian coin is worth $1. You now have 100$.

If I remember correctly that is how you make profits out of investing (sounds logical to me). I am however not sure about it so take it with a huge grain of salt.
