@ethan_ng, i too have seen the giant buy and sell walls on Bitfin. On BTC/USD, ETH/USD, and ETH/BTC. Ive seen blocks totalling $7 million + at various price points within each of the pairs. ETH/BTC has seen MASSIVE manipulation over the last few weeks. Unprecedented. Someone hellbent on keeping a lid on ETH. Someone who has access to unlimited USDT. Someone who also wants BTC to rise. Check out the USDT supply statistics and the corresponding BTC price movements within minutes of the USDT token increase. I am talking 30-40 million dollars. 30 to 40 million dumped into BTC in a few minutes. A legit 30 million dollar investment isnt going to be a market buy, it would be a slow trickle limit or some small markets over time. Everything I mention is on BITFIN.
