As the market is getting bullish, there's going to be more newcomers trooping into the crypto space and scammers use the opportunity to launch many fake projects hoping to scam unsuspecting inventors.

Actually, there's no season for scammers, so long there are gullible users who will take the bait.
But when bitcoin or crypto market is getting much interest because of the rising prices, and so the number of scammers.
