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?
Any amount of money is fine to invest. I know people that have started with 50 USD or 50 Euro and have done amazing things and have been profitable. The important thing about the money you invest is that it should not be money that you might need to take out for something else. This way, if a coin you choose to buy goes down in value then you can wait until it goes up in value before selling it. With very few exceptions, you should never sell at a loss. Even people who bought bitcoin at $20K should be ready to hold it until 2020 or even 2021 which is likely when bitcoin will see those high levels again.
Learn to read stock charts. Pay attention to RSI, moving averages, and stochastics. Try to buy when RSI is low.. at least below 40 and when the moving average is also below the trend.
Good luck to you and always remember. BUY LOW SELL HIGH. If you take out money for a loss because you needed that money to buy food then you really didn't have enough money to invest with and should reevaluate your life habits.
