If scammers aren't attracted to it then it's not actually worth what's been priced at, scammers only go for what they believe have potential and the cryptocurency industry is full of that potential. Bitcoin shouldn't be blame for all that's happening, I'm pretty sure it never intend for it to turn out this way like there's even more coins than investors.

Bitcoin was only interested in making us financially free, been able to spend your money without the interference of a third party like the banks, Satoshi knew the fiat system was failing and been corrupt so he introduced a much better way to carryout our finances but as usual humans, we always became greedy.

Th alternative industry has done some good as well bad to the community, assuming the industry wasn't exiting then we won't have had some of the amazing projects that are currently exiting and potentially been in developed to be released in future.
