15BTC sell wall is nothing really, maybe scary to the small time trader but dont freak and panic sell. Me and my partner have just over 20 BTC invested in alts and about 60% of that in Cinni, so 15BTC is nothing to be worried about. Just take the chance now and buy up some Cinni to hold by the end of summer that small risk investment could be worth something serious and you got to be in it to win it, you will never make a fast profit here but in the long term you could make something huge. So just take this time to buy and then hold and stake, this is the chance for anyone who missed the BTC train. Just buy into the whales walls and eat it away chunk by chunk until he has nothing left to play with, he may hold alot of Cinni but seems happy to give them away to us all for a great price. Just needs some well planned trading to start taking him out, which would mean well timed big buys between the whole community at the right time, just need to set a few sells wait for the whales big wall to come then pull all walls below it and buy into his. With enough buy support and timing those buys at the same time the whale wont be able to hold out much more.
