so I have around 3 bitcoins in hashnet and was going to transfer this to my coinbase account, but have read a few negative remarks about them here, just wanted those who know opinion on them are they safe ?. going to buy a lot more coins over the coming years and really want to not worry about them till the time comes to use them.
thanks guys I know many questions are on these matters but for newbies I need to know long term its safe.
Well, if you don't control the private key, you don't own the coins. It's simple as that.
Coinbase has a pretty good reputation as an online wallet, but anything can happen to a company. Like cryptsy, they can close down and pull off a runner any time. Because you don't have access to your private key, you lose all your bitcoins. I suggest you use a cold storage facility to store large amounts of coins instead.
