Let's make the buy wall at 3650 the floor! If you believe in EXE, then throw even a .1BTC buy order up at 3650. A few BTC stacked close on the buy side is what this coin needs to keep the network power up and this coin strong.
I've been watching the big order (15,000+ EXE ~ .5 BTC) @ 3500 satoshi since yesterday to see if it would grow or move. It's stayed at about the same price and size. I think it helped support the EXE price when it broke down through 4000 satoshi yesterday. Right now there are eight 1000-5000 EXE orders just above the big one. Maybe some of these are altcoin mining profits intended to be coverted to EXE but they also add to the wall being so close to it.
I've just put in a bid for 3000 EXE @ 3500, to increase the bid there to 18,417 (0.645 BTC), having sold my NXT position to raise some BTC. I don't necessarily want to sell those BTC right now (for the sake of diversification), but I'm willing to risk them on the bid wall.
I'm continuing to mine profitable altcoins and buying EXE with the BTC proceeds, usually in the gap between the ask and bid price on Cryptsy. I was mining FLT but after only a day the price dropped too much, so I looked for others. I tried to join manicminer.in (as recommended by reddit user /u/winterm) but my cgminer didn't work with them as they warned. I tried switching to bfgminer but couldn't get it working so I started looking elsewhere.
I found a nice multi-coin pool hash-to-coins.com. It's small but it's been working well so far with cgminer. This pool tracks the most profitable coins and allows you to switch between them (or split your workers between several) with a few mouse clicks. I've been mining FLAP for a day, although right now transactions are frozen due to a hard fork. The operator of hash-to-coins.com is right on top of it. For the first time I've tried withdrawing my coins directly to an exchange (Poloniex in this case). I thought this was not recommended but it's working fine for me and saves the trouble of going through my wallet, or even needing a wallet.
