I think 5M in the last 24 hours is a LOT. Even more considering that everyone now is like stand by because of mtgox.. I have my btc in some other places like stamp, btc-e.. after all this normalize i'll send a few more to bter. People now is gaining money surfing this btc waves.. and some other, the most, panic losing money. Relax and wait all this mtgox nonsense get solved and nxt will grow.. i don't know if you know but next weeks are gonna be full of good news and new releases, event, etc.. for nxt. Good things happening. Price could easily be double in a few weeks.
There is many things happening. One of the following is this.
AE
11th of Feb - public test
Xth of Feb - release
Big amount of REALLY talented people working on NXT and this just started.. Do U really think this is not going to grow in the next weeks? There is things being done that i didn't even imagine they were possible.
