People switched to gold and precious metal, that was the altcoin season right there, it's like retailers decided to do something different this time, but I can't deny the fact that some altcoins did ran incredibly well, more than Bitcoin, and all these top altcoins...
Of course mate, that's the magnet of attraction from the altcoins market which has year to year gained consistent patronage from crypto investors. But figuring out to identify which altcoin among thousands of shitocoins that would perform well before even thinking of tremendously well is where the
gambling come about. The chances are extremely low and that's why holding altcoin for long is just too risky to try when it can be done with bitcoin.
