If your question is how to find out kung legit bago mag launch ang coin? Tingnan mo kung meron escrow if meron ICO, or kung pinapamigay nila.
For everything else, it's very hard to figure out, so the best way is to just wait and see if it gets traded on exchanges. It's never too late to join a coin.
Dati ang Litecoin umabot ng $40. Ngayon it's about $4 only.
Yung ETH, tunay na project, pero, wala ako masyadong tiwala sa systema nila, palagi na lang nagkakaron ng isyu, fork, hack, or whatever.
I think XMR is the best investment now and it has aweken just recently, so I think it is good to buy now while the price is so cheap, I am buying XMR at 0.02 but the price has drop hard but I am not losing hope so I will still hold then.
