there are so many cryptos and I find it hard to identify the ones where I should have a closer look.
Obviously one can find cryptos e.g. by listening to shilling on Reddit. But I'm looking for more professional sources like YouTube channels, free/ paid Telegram/Discord groups and so on. What do you use?
To find good crypto's first of all you need to shave some sound knowledge on both fundamental wise and technical wise so that you can take some action on them.
Fundamental wise first of all you need to do some research about Crypto coins which are on trend and also they must have some good service or strong reason for buying it and then check it whether it is undervalued right now from the current market conditions or not if it is undervalued then you must go for buying it. And then once the fundamental analysis is passed then you should move on to the technical analysis for timing the entry and exits. Also, use screener for listing out the top 5 trending coins which are good for buying right now and then take entry according to your strategy and plan your money management techniques so that you control your risk according to that.
