hello!
for me being new to cryptocurrencies i would like to know from where do you get your predictions about the price of not just bitcoins but other cryptocurrencies?
I got it from the channel telegram and some of my analytical techniques.
Looking at the charts and previous prices are also needed because with it we can know the highest price of a coin in a certain period.
Try to learn Bollinger Band then you can know at what price and when you should buy or sell your coin.
