Why do you want to store your coins on an exchange? If youre not using Bitstamp to trade then get your coins off there. You should be the sole owner of your private keys, if they are exposed to anybody else then those coins are not yours.
Use a paper wallet, hardware wallet or bitcoin core to keep your bitcoins safe.
Jessus fu... christ... im not an idiot

... I want to use these for a little (test) trading... Also someone (not me at current stage) would like to sell some of his bitcoin where the price is overshoot (like it was at 1200) and as it will be at 10 000 and buy back lower.
