For those of you who do a bit of daytrading, do you sell and buy in the exchanges, like bitstamp or not? Isn't it risky, when something like MtGox could happen? I want to hear some thoughts on this!
Yes it's risky on the high volume exchanges, and there is always the risk they could get hacked and you lose the lot. Coinbase is insured, but lower volume than the bigger exchanges, and they have more restrictions on what you are allowed to do with your coins. Gemini is also insured but has extremely low volume, though it might go up.
Thank you for the answer. What about btc-e and bitstamp? In what volume will things get risky? Like 100 bitcoins, 1000 or even a few, like 10?
As for which of the two is better, I personally prefer Bitstamp as they seem more serious and less shady than btc-e.
I mainly trade on OKCoin, the degenerate that I am
Note though that Chinese exchanges are probably the shadiest and riskiest, with the trade-off being by far the most liquidity, best fees and margin options.
