The sum of joined people in crypto is growing day by day and  I am sure that it is cool because the profit I increasing too and incomes are so high. I am here for so long but I have never do deals in crypto by myself. But I am going to invest now and I have found too many resources like exchanges, wallets and so on. What can I use now as a new participant of this deal? What ones are more reliable for the side of the price and security? With what amount of money I must have for the beginning?
