Such projects are still there, but there are very few of them. The company you joined is also important. Twitter and Facebook are unlikely to bring a good profit, like a signature company. I think it's worth writing articles or joining a company of translators.
And right now, the chance of getting high rewards like what the OP is asking - $350k is really very slim to no chance. The times have been changed in crypto, it is not the same as 3 years ago. So right now, don't expect to gain such amount from bounties alone. Be happy if you will receive few hundred bucks from the tokens or coins that you will receive from bounty programs. Don't expect so much from bounties now, make yourself productive in other alternative options to earn crypto like trading.
Getting a good amount is possible if based on the original token value, problem is, the value will drop once it starts trading that's the challenge and this needs to be change, actually, if we are all hoping for some great bounty reward, all we have to do is just to hold it and wait for the altcoins season. I know it's easy to say but hard to do it, but with trust that the market will once again become bullish, we should remain optimistic.
