Why has the price gone down so much?
Buying now will be a good decision. its too cheap now! and you can easily double or make atleast 150% Roi if you sell at the right time.
I Just bought more at 61 sats and set a sell order at 120sats

easy and just a simple waiting game.
I totally agree with you about the price movement of SDRN, the project developer is an active fellow and he have not abandon the project since the distribution of 40,000 sdrn airdrop to everybody.
The release of different version of sdrn wallets simply shows that the project is alive and any positive thing can happen.
