There seems to be a withdrawal transaction from my Cryptopia BTC address to some address I don't know for the amount I have in my portfolio there + an additional like 3 BTC worth on top of that. It's unconfirmed but I have no idea if this is normal.

Any help?

Right now Bittrex doesn't take new accounts and I'm not too comfortable buying from Cryptopia, HitBTC, and Poloniex. Either fees seem high or people have trouble with withdrawals/losing money/no support.

Any help would be great, thanks!

Main questions are in the title, but an additional one is, do you guys use a wallet that's offline?

sorry if my questions are basic/doesn't make sense. Still trying to learn the ropes. Thanks

I'm extremely new to the cryptocurrency world. Stumbled across this forum and found it pretty interesting. After browsing through some topics, I feel a bit overwhelmed. I'll keep looking around but if someone can direct me to well written resources that break down bitcoin, blockchain, and crypto in easy to understand/digest ways that'd be great.

Another question I had was, is there a way to invest in partial bitcoins? For example, if I only have $100 to use, is there like some mutual fund equivalent to owning bitcoin?

Thanks in advance.
