The most important thing that EDC continues to grow when market falls. It constantly grows + extra profit for the participation in leasing program.
Yes, it can give you double profit if you manage to get out of the coin on time. But often this cannot be done, since the coins are locked until a certain time.
I agree that it is dangerous to lock up the tokens, but I participate in leasing program and I see how it is profitable. When I bought tokens they costed $0,0030 now they cost $0,0052. Plus profit from leasing.
I agree that lock up tokens is very big risk, but I see how actively developing EDC Blockchain. If project will continue to develop the price of the tokens hope will grow.
