The Devs need to get paid in USD or BTC.
Devs usually get paid in the shitcoin they are producing so not only do they have to dump it to get real money to live on, they have to sing its praises regardless whether they believe in it or not.
let me just stop you there.
this is the problem with altcoins in my opinion, the devs are looking for making money or worse to live off of the money they earn from developing their coin!
so when your goal becomes earning money first then developing you end up earning a lot if you are paid with your own altcoin and hype pump it to dump and make money.
Satoshi was never thinking about making money from bitcoin and those coins he mined are still un-touched and look at where bitcoin is today.
