CoinBase is a fishy service. It is better to avoid them. Use BlockChain.info
i'm interesting with your statement
what is the reason you said coinbase is fishy service ?
i think they are good exchanger, many ppl buy BTC from them
what I saw till now i am using Coinbase more then 2 year and no problem at all till now.
I think so. Coinbase is very good.
All web wallets are at least somewhat suspect, as it's impossible to be truly secure without using a local wallet or preferably cold storage.
However, I've used Coinbase for several years (as an exchange, not a wallet, though I do keep ~$25 worth of BTC there for faster trading), and I've never had a problem with them. In addition to that, the complaints about trades being labeled "high risk" and failing seem to have dropped off lately, and the considerable amount of venture funding they've received and the regulations they comply with also make them more trustworthy. However, always do your own research before choosing a web wallet or exchange.
