I'd recommend you to create your own portfolio even if it's not crypto/bounty translation experiences. Bounty managers like to see previous experiences to get an idea about your work even if it's not crypto related.
By this, if you never translated before, I'd recommend you to start on your own translating onepager documents or ANN and use them for a start
Well, I guess the main question would be, where did you get those emails from? I have a crypto email and all of a sudden I start receiving like 10-20 emails everyday about shitcoins or shaddy bounty programs. Hope you don't spam people with with you huge list
It's good to here from others, but don't take them as an investment advise at all. Personally, I see BTC, NEO and ETH are good for long term. However, I like to diversify my portfolio so nice if you look into infrastructure projects and exchange tokens such as Binance or KuCoin.
