Not from devs, dump is from existing users and thats normal, 1st exchange didnt bring us new users, it was there just so that old users trade a little - and of that small trade volume at start lots of users buy cheap now from users which are selling cheap.
Next exchange is bigger and price will rice from current 850-900 , but real rise will be when we hit CE and Cryptopia when they reply.
I am 100% sure that in 5000%/10000% coin only rookies sell on 5000% and smart ones buys from them and hold and grow to sell day by day at 10000% when price is enough low so that everyone can buy. Remember - at 10000% every single user can double their coins in 3 days.
For those who cannot buy now and are low on coins i suggest they join official pool with zero fee and same day withdraw - it stakes currently near perfect well above 13%
Happy Staking!
