Couldn't have said it better . People who couldn't catch the Bitcoin train, buy it in hopes that maybe one day these altcoins will bring the same result but so far nothing has came even close to that.
They are trying out hundreds of ways to do things and finding out good ways to do things and ways to definately not do things..
I would much rather them be experimenting on shitcoins rather than experimenting on Bitcoin itself..
Also some alts are good companions to BTC IMO for there strengths of faster block times and some have increased anonymity protections that some may see very useful.
I guess this is the reason behind some of the coins to test out new technology but how to know which ones are shitcoins and which are not?
