Sometimes you do not have choice. For example, many tokens is possible to sell only on Yobit. It is good that there is a choice of the exchanges in the case of EDC blockhain.
If there is no choice, and the asset is being traded only on this exchange, then I am not interested in this asset. All assets that I got as rewards in bounty campaigns are not traded on this exchange.
It says only that you listen to the opinions of others. You can not talk about something without trying it.
This is called learning from the mistakes of others.
Did you jump into the draw-well? You say that anyone can jump into the well?

I agree that the choice of bounty is very important. But very often tokens are not traded at all even on Youbit
