Hello, everyone!
I need some piece of advice from the experienced people.
I dared to start trading , I have enough funds to purchase BTC or ETH, but I don't know, where to create wallets and how to manage them (I mean safety issues)?
Can anyone share their experience about that?
Since you have enough funds to trade, I'd suggest you create a blockchain wallet via blockchain.info. It's the best wallet you can ever find. This is so due to the safety feature of the wallet.
Concerning trading, I'd suggest you use Poloniex or Bittrex. I've been using them for a while now and they are very good trading platform.
