So, looks like Lisk team move 940 BTC from ICO fund
to Poloniex to made big buy wall and pump Lisk.
Hope I am wrong, or this can be very bad for Lisk

Thats a fake buy wall.
365 btc buy order on 5700 satoshi, which is impossible
to reach because LSK price is now almost 3x than that.
Lisk team convert BTC to fiat money
