That's cool - I like to hold onto my masternodes, but it's true you can make a lot of money liquidating them during a pump. Hindsight is always 20/20 - I too kicked myself for not selling or buying at the exact ideal times last night and this morning, but I have to remind myself that I couldn't have known where the prices were going at the time. Sibcoin sounds interesting - I have an affinity for masternode coins - good luck with that!
