Regarding to the topic if the price goes down it should not hurt us.
I wouldn't be so sure of that. If Bitcoin and BU form two seperate chains, then prepare for prices deep under the $1000 level. Especially when exchanges will allow do trade both coins simultaneously (where obviously BU will be the altcoin), then the panic will be complete.
even if the price goes down we have the confident again the price will raise which is why lot of people of joining into the btc world.
Long term is always the best to focus on as we indeed have seen the price go up, even after experiencing the worst possible scenarios. But the short term can look pretty nasty if things go in the wrong way.
if the price goes down then buy the coins so you can sell when the price is high.
Best possible option. Buy the panic (in case the market goes nuts).
