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.
In my honest opinion, the best way to make predictions is to look at the predictions of crypto experts and go with the one having more logic's and support. That way a person understands the market better. Reading charts and looking at the stats is somehow cumbersome. Besides, the predictions are always on the mark, never wrong or at least not so far. Easy way to do the job.
