Why do you think this? Can you please explain it to me, why won't it work good?
I can't really see any problem if I don't mind about banks that can't control it..
2. Satoshi owns more than 1,000,000 BTC, can you imagine what would happen if he decided to dump?
You assume Satoshi owns 1 million btc, which is hard to believe. He wasn't the only miner back then. It was insanely easy to get a ton of coins mined in a very short time.
The value back then was barely worth mentioning; $1 would buy you over 1000 bitcoins. Living with the fear of seeing these potentially "lost" coins being dumped at once is not the way to go.
