Another thing I would also recommend is paying attention to media.
Reason I say this is because:
- feedback is important whether positive or negative
- critical reviews by professionals
- using certain things such as telegram, Facebook, Twitter and various other tools play an important roll on how a project is coming along.
Afterwards comes down to your own judgement whether you want to invest or not.
Well, that is if you want to go with the fundamental analysis aspect of trading but I would not recommend just that since you cannot do with it alone to be able to get the best of the market. As far as I am concerned, it still makes more sense making use of technical analysis with your fundamental analysis to be able to make the best decision in your trade.
I really do not always use most of the time fundamental analysis though, and I have been doing hugely well. As long as you have great knowledge on how to analyze the market and do your thing effectively, then I see no reason why you should have a problem at all, no matter your style of trading.
Moreover being a long term holder, I do not worry on where I am buying because all the prices are good to buy and hold when you are targeting millions of dollar value for your bitcoins. This is what exactly I am doing. I am not deciding my buying just by price levels of bitcoins but by the available excess funds for that month.
