Coinbase issues?

I'm hoping someone who sees this has some answers. I'm hooked up with coinbase as a whole way to bring the fiat and crypto together. I'm not sure how this platform compares to others out there for this thing but when I was getting into Steemit this is the exchange that I started with. Probly because it was available in Canada.

Any better products out there you can recommend?

Anyway about a month ago I made my only transaction. I bought ten CAD worth of bitcoin so that I could transfer it into steem to play around on here a bit.... Research.

What I found is that coinbase is an expensive place to do business. It cost me more in fees than the value of the currency I was trading
.. I haven't found out yet if that cost is scaleable to the amount traded or if the small flat fee they charge just took so much out of such a little transaction.

Again, any better options out there to research before I get serious about this stuff? I'm here to have fun and MAKE money not spend it all on fees. What a racket!!

Anyway I got a notice today that coinbase took another ten bucks out of my bank account. Wtf??!! I didn't make any transaction and none show up on my dashboards...

I look further into it and found that the cash for my transaction last month actually came out of my acct. Two days later than when I transacted. Then a couple of weeks later they reimbursed two small fee items and then today there was a refund and then a 're-buy through my account.

Anybody know what the skrunk this is all about? It has me feeling concerned about security for sure. Is coinbase all that secure?

Sigh. More crypto Noob questions. I'm getting these out of the way before I get heavily vested. I guess it will make that a lot less stressful.

Please. Any tips or comments much appreciated.
