When I first came across is particularly statement (crypto is just like gambling) i was like those this person really know what he or she is saying. But after given that statement some thought I came to understand that there is truth in the statement. Because if not for the money that we can earn from cryptocurrency investment I don't think many us would want to use it for transactions which is the primary use that was first mentioned by the invented.
You and whoever you derived the idea from are wrong, the misconception didn't start from crypto, but traditional trading in its widest sense. In the end, a sensible person will know that trading is not gambling, but still, you can gamble while thinking you are trading. The same goes for crypto while thinking you are trading/investing in it.
In a nutshell, your expertise in handling the two distinguishes you from being a gambler.
