Not really. Bitconnect has been to know to be a ponzi scheme for quite some time now, and it didn't affect the crypto community or cryptocurrencies in general. Actually, the crypto community has been very vocal and very active about letting people know that Bitconnect was a ponzi scheme.
Now this is only the beginning, there are still a lot more ponzi schemes and scamcoins in the market, it's a matter of time before they also get exposed.
Yes - and I don't think that many new people were invested in it. Most noobs start off at Coinbase where they offer only BTC, LTC and ETH. It was some greedy people on this forum that piled into bitconnect, but as they're a small number, it's just another crypto scam that doesn't affect teh big picture.
