I can't say I think that is a bad thing 
Yes it is indeed a bad thing:Look at what has infested our ecosystem within the top 10... 2 debt coins (Ripple/Stellar), a Meme coin (Doge) and a scam coin (Paycoin).
Despite languishing, at least Bitshares and Nxt have real developers and ingenuity behind their projects. You have to respect that.
The rest of our ecosystem has been overun by PoW cloudmining ponzi's and PoS ICO scams.
And those that aren't directly involved in the scams are fine with profiting off of them because hey, may as well make some money
off that affiliate program or day trading on the ignorance of the uninitiated. The whole ecosystem needs a colon cleansing.
its true that most the alt coins at the top are long term scams and short term scams, and mostly copy coins, but there are some good ones and original ideas. These will eventually be weeded out and only the good ones will remain.
nxt is not better or worse than bitcoin at least not at the moment, its just different, and to keep crypto moving forward we need lots of different.
