is the bitcoin is really safe? where i can put my money for example blockchain wallet never scam me? or CEX.IO is the bitcoin safe 100%? like the bank mean if i deposit in any company money will stay for ever or maybe i the company close any my money gone in this wallet? and where is the trusted list for this company? Kindly answer me about CEX.IO ... BLOCKCHAIN ?? ETC
I would personally skip out on Cex.io, but blockchain.info, Coinbase, Xapo, other similar wallets and so are typically quite safe and free from most issues. I used to use Coinbase (and I was pleased with their service) but I opted to change to Blockchain.info because there had been less controversies with them in the past. Xapo offers a Bitcoin debit card too, so if you're interested in that sort of thing then you'd be looking at Xapo as a high choice at least.
Meaning in your answer CEX.IO is not safe? Well to that information you gave. So far those you mentioned I don't have quite familiar into it except in blockchain but the rest are not. I think I will try Xapo to sign to find out the good thing they can to their client.
