This is pretty similar as with stocks. There is sooooooo many of them. Some good, some bad, most crap.
NEVER fall in love any of them either.
Although, I suspect you might be trolling, I'll bite:
It's tempting to compare buying stocks with cryptos; but it doesn't really hold - when you buy a stock (at least one listed on a regulated exchange, and not the pink sheets) you're buying a share of an established company with a documented financial history and (one would hope) plan for profitability. Crypto currency isn't really a share of anything; it's an unregulated medium of exchange, which one hopes will accrue in value based on the perception of its utility and trustworthiness.
