I want to start investing for ico and trading. Please to help from where should I start?
Your question is not unique, you see. There are many topics here with all of the answers you're looking for. I don't think someone will start explaining you everything again from the start, probably for the hundredth time. You've almost made a half of a deal. You've created an account here and now you have a free access to the tons of different kind of information. All you need to do is spend some time to search, read, learn.
What needs to be prepared and cared for before starting it?
You need to learn at least some basics (the more you know the better) about ICO, trading and crypto in general before taking any action.
I prefer to run trading than ICO. because I see the development of profits that I may achieve much higher there Trading. other than that to minimize the risk that I received in the future from ICO. other than that a lot of news for the ICO scam and experienced piracy where.
