at this point it takes at least 1 business day to get money from one bank to a bank in a different country in europe. what do you guys think about this? will it be a positive or negative change? i actually like it since i can send money from my bank account to an exchange within europe instantly, and basically the same goes up for when you request a withdrawal.

it's weird, but somehow bitfinex is gaining back trust in the market as once again it started initiating a pump where china followed with a massive green candle. take a look at the charts and you will know what i am talking about.

for example, when my wallet has a balance of 0.55btc, and i want to send 0.20btc to a certain person, the remaining balance, or a part of it, goes to a different address (change address), while i want everything to remain in my main wallet. i know it's possible, but only not sure how to do it. i am working with bitcoin core 0.12.1.

i was reading something about wallets with outgoing transactions are less safe?

so if i use my wallets it is less safe. what is best wallet?
