Too bad I haven't managed to invest in crypto back in those years. I could've invested a little in Litecoin if I was still like a little newbie back then.
Don't feel too sorry about it. Maybe you would have done the right thing at the time and invested your money in Litecoin, but you could have also invested in Peercoin, Devcoin, Feathercoin, or any of the other projects that are now defunct and useless. Imagine you held bags of those expecting better days to come? Your portfolio would have been looking much worse if that happened.
Exactly and in years to come, same story would be told about coins currently making waves in the market especially the Defi, NFT projects thinking they have forever to dominate the space. Time will wipe them all out or decrease their value just as other projects before them are experiencing, history always repeat itself and those would ignore this surfers.
That you miss an opportunity to cash out from this trending technology the (altcoins industry in general) now doesn't mean you can't do so in the future with far superior projects which hopefully will be developed with less focus on quick money scheme but actually having interest in helping the industry achieve world greater things.
