DANGEROUS ERA OF COINS - be cautious

The way and manner crypto-currencies are creeping up here and there could get to a dangerous dimension in the days to come. I have lost count of the number of coins so far in existence and more are coming out every other day. The question is....Can this be sustained?

Lets take a look at bitcoin and the manner it took the crypto-currency world by storm hitting $20k per one bitcoin but has lost over 50% of its value ever since attaining that height.

My concern is that people should trade with caution as it concerns cryto-currency just like forex trading. It is only when we view this with caution that we all can be well alive to witness the tremendous value we will all achieve or the losses we will all incur from using these crypto-currencies.
