Whales can dump at any given time, I prefer when there is a large community of average investors, then token price will be more stable.
Well let them dump menapay, i think the menacash serves that purpose of stability, meanwhile you could pocket cheap menapay

But to reach its financial goals big investors can be necessary. It's hard nowadays to find sufficiant funding amongst the community. Sure, whales probably have gotten good bonuses but therefore a lot of projects have a vesting period for their tokens to prevent dumps.
