So i am looking for doing with the safest investment strategy.
How do you think about the usd lending on bitfinex?
BTC lendinh on bitfinex or poloniex?
Which one is more safer? and Can you recommend me for lending bot?
Being stress is part of trading life. You are claiming having BTC100 on exchanges but still having a feeling like that? How come? I can't picture out your situation. Since you have decent money on hand, being stress is just part of the challenge and you will never think like that especially with the word "safe".
I don't know if you are telling truth here about your hold funds.
