Still, now new altcoin is being created, but they don't use BTCtalk anymore.
and here's all bounty's are scam.
How you do able to know that there are no new altcoin being created? Try to look the bounty section or even with altcoin announcement then you would see tons of them are making new one
somehow the extent or the numbers arent the same into those year where ICo is still on extreme hype but still you can see some numbers who do continually to create for those coin developers
and hoping to get some marketshare(this is only for those who are making one legitmately.)
When it comes to scam aspects then its pretty normal.This is why as an investor you should really be careful on choosing which one you would invest on.
