BNB was once 6$
ETH was once 100$
BTC was once 3500$
This is what happened to those that invested in bitcoin at the end of 2017 for 20k, but anyone that invested in a new altcoin is probably nowhere near to recover their money even with this bull run, so anyone thinking on investing right now should do it only in coins that have a strong future so even if the market happened to crash tomorrow you will have a chance to make profits if you hold long enough.
