It's possible, that's not called luck because these coins are indeed legit.
KMD for example is one of the oldest coins I've invested in the past and although it dump like 20 fold times from its ATH to the current price, I still find it attractive. IMO, it's the market that will dictate a big pump like our expectation but what we just like to see is just a recovery price, not really a big thing since the ATH is still too high, so it's good to expect that kind of growth.
Possible,,, but the reality is you can own a legit coin and not make money,,, while you can also own a coin that is an actual scam and still make a lot of profit. You only need to look back at some of the coins from 2017 and 2018, where people who left actually admitted their company was just scamming people. And their coins made a lot of profit (until they dumped).
Very true, People invested in anything which came up and became popular by their marketing strategies. Not every coin was a successful one or even genuinely working for crypto for that matter. There are many top coins which may jump to 3x-5x in a matter of time but staying there would be an issue in this volatility. Hopefully, we will see good alt season this time and make some profits from them.
