While we are still waiting for the faucet and trading platform it is much better to continue holding your Mrai or sell not below 450 as the difficulty to earn it was too difficult.
Well this story has two possible endings
1) all gets back to normal and eventually an exchange will put xrb online
2) all gets even more worse than it is now, interest will fade and price will drop like a rock
Ppl who believe in option 1 will hold on to their coins or will only sell high.
Ppl who believe in option 2 will sell their coins and try to get as much for it as possible but they are happy with almost everything they get offered.
Everybody should choose for themselves what they believe and which strategy they take.
