I sell my bits when I'm sure the price will go down enough for me to buy my bits back at a certain profit.

And if I don't think that's going to happen?  Or am not sure the dip is going to be deep enough to make it a better risk than plain gambling?

Right, then I just don't sell my bits.

(Haven't sold a single bit in a long time, other than helping others get BTC and offsetting that with a buy somewhere else)

I usually only talk about positive things, but since this is a post of Bear, let's bring out some bearish facts

There is a possible hard fork in the near future, where user might be forced to switch blockchain. If you use original software, you will stay with original protocol, and if you use a new software published by btc foundation, you will use the new protocol. Both protocol do not accept the block on another chain, so coin generated on one chain become invalid in another chain (not sure if old coins will  be affected)

I don't really understand the necessity of such a hard fork, but anyway core developers said there are this this and this reason that we should/should not raise the transaction size limit, the debate has been going on for one year

The debate splited into two different political view regarding how BTC will perform in the future, I think this revealed a potential weakness in BTC: Currently there is no good decision making process established in btc community, if some developer with big influence decided to make a change in protocol, while some others do not agree, they might go ahead and make this fork, and we will get a split after the hard fork, so that some group of user stay with the original, and some other group goes with the new protocol, if that split is 50-50, that will almost immediately cut the BTC price by half. It is not about the technology itself, it is about people's trust of blockchain

I had a poll for this, have a mixed result without any majority:
