Honestly, it’s probably a mix of both – a bit of luck and being in the right place at the right time.
I agree, with strategies and a stroke of luck makes a good combination. While the exchange listing "good" projects, this is subjective and depending on how we look at them. They're only good if we make some profits on it but someone who's enthusiastic about it is a different thing and short profits won't be an important matter to that person. I think that many think about saying that listing such "solid" project is overrated. If you have come early to that coin and you're able to still make some profit while the volume is high, that's on you.
