I was confused with few things like how to trust any crypto currency(Small cap Coins)? was TA enough?
TA does not work for low market cap coins with little to no trading volume and/or trading participants. This is because TA measures sentiment thus needs adequate data samples.
Then, my friend said, know about the team that is building it if that has the potential then you can easy thrust as the good team will always take the project higher etc.,
Well, you should treat this case similar to business valuation. It would be best if you know the product (MVP), team, leaders, funds, etc. If you do not have enough experience in investing, I suggest you not to invest for a couple of months while learning about this industry.
This statement made me more confused as the person or team behind BTC is unknown but, still people believe in it. If so then should I be worried about the team in case of other coins? So., Confusing
Actually, only the founder/inventor is unknown, and we still know who the "backers" are.
