There is only one reason, the inflation rate of the coins are much bigger than the community can support. @FreeTrade has a good analysis how many btcs required to support a coin each day. Altcoin is a big family, money move in and out any minute, eventually they should be treated as one society. The inflation rate in this society is way too high.
so wannabe devs, please stop making new coins, you are not going to get your time of money back.if you need so many btc premine to support your expense, why don't you just buy off the entire stock of some current coins in teen satoshi level. it has pools, has exchanges, saving all your so called cost, and your time as well.
ppl, stop buying ipos, stop buying coins from those ipo investors, the ongoing demand cannot support newly issued coins, you are going to see your investment halved, and halved again and again.
