Wow, you have really inspired me, thanks. I will start from learning process. You are right.
Thanks for your help.
But what is about how can I start to make deposit. Do I need to creat some digital wallet? If so, where can I take it?
Creating a wallet on exchange or any third party site in which you do not control the private keys is not advisable at all.
First , you need to learn a bit about crypto currency so you can understand basic concepts. Users already shared the books and thread in previous post, so go through them once.
Even when you trade , it will be not advisable to leave your coins on exchange due to risk involved and make sure you choose your exchange wisely. (there are lot of scam exchange,coins,people..)
Be safe.
