Not sure if I understand correctly. Say I buy coin from Coinbase / Localbitcoins. If I want to move what I just bought into another wallet, it will be charged?

I also heard when you buy, in general the buy price is about 3% higher than market price. Same when you sell. This mean if I trade at 6% higher, it will only be breakeven minus the fee (unless I keep them in the online exchange wallet)?

Another question is, if I want to keep coins in H/W wallet for safety, I have to consider fee and the time for transaction confirmation which is tired to the fee. If there is a big drop and gain, everyone wants to do the same, the time will take longer even if you choose fast transaction.

First question is answered above pretty much perfectly. Second question: fees and speeds are dynamic, if there are a lot of transactions because everyone wants to move bitcoin then it will require a higher fee for a faster confirmation.

It's right. When bitcoin's blockchain mempool becomes bigger, so transaction fee is increasing respectively.
