I think not, remember a lot of thieves in the cloud, and we don't know how safe is if we save cloud, I suggest stick with the bank because it has been proven to be safer than cloud.
We should look for safe storage temps of course. Storing in the cloud is not a bad thing, you have to read how the system works so you can deduce the security standards they use.
i personally have no idea about that. i like to know about it, but i do not know that from where i can get information about cloud storage and what is the advantages of cloud storage because i am simply trading altcoin, buying low and selling high.
