BTC can gone in 1 sec, and fall at 1 usd, because I do not want to pay BTC above 100 usd,
just in case it BTC be recognized by all world bank, then I can pay bitcoin 1000, 5000, or 100 000 usd,
for now 100 usd is maximum.
You don't want to pay more than 100 usd for BTC, because thats all you got.
you're wrong, I have only 5 usd, 100 usd is so much for me.
