Locking up bounty rewards is actually to prevent huge dump when listed on exchanges but i believe it was unfair of the team to have suddenly change the rules of the distribution. Even though they have the right do so i believe they could have better communicated this with the bounty participants other than slamming it down their throat like that.
This can be problem, but there are ways to prevent dump and bounty huters form selling all tokens all at once.
No, there can't be a problem. I had explained that already in my previous post:
https://bitcointalk.org/index.php?topic=5103256.msg49848985#msg49848985And I'm going to stick with my opinion unless you show me a bounty campaign that allocates at least over 5% of the total supply of tokens to their bounty. There are no valid reasons for locking participants' bounties for months, in my opinion.
Well for exchanges that have low liquidity the price can change drastically with just small amount of sold tokens. Also not all the tokens are released immedeately. Investor tokens are usually released first, then bounty hunters. The team member tokens are sometimes locked for some period of time (few months).
