So I made my first purchase on Coinbase and it limited me to $500. I verified my ID and my credit card. Is there any other way to get more BTC sooner? I dont want to wait the 3 days or whatever it is.
You could also open an account at Circle.com.
What is this service and how I can be sure that my coins are safe with them? I thought that any online wallet or deposit is generally considered not viable method of keeping your coins.
As service, site or deposit can be hacked, and probably will at some point.
