All of the little people put together don't have as many BTC and SYS as us bigger players. For us, 25000 is pocket change. If I put up 100000, another big player would buy it all up in one go. It is the small guys with only 1000 or 5000 or 10000 SYS to their name that are fighting each other to sell cheapest. If all of you would just park your SYS together at say 570 or 600, we would still buy you up at the higher price - because we can. Quite a few of us have 2.5BTC or 5BTC or 10BTC to buy with. So, when you all sell for 424 and 380, you're making yourself poorer and us richer. Have some respect for yourself and try to sell at double what you paid. If you only have $0.5 dollars worth, why sell it for $0.25 when you can double it and have $1.00 to buy a whole candy bar?
How do you do that? There is basically no volume to buy 25000 without jumping the price out of the 400 range.
I started with 3 BTC. In a few swings from 400 to 500 I've made over 1 BTC. I will continue to do so until I double my investment, then I will sell half and let the rest sit in my wallet, while people like you will still have what they started with. This is a speculative coin now, not one of those that have huge price spike after launch. And I hope we will swing like that for many months, because it is good for traders.
You are not doing this atm though. There isn't much f trading going on in sys for the last days.
