what was your worst mistake ( in the very beginning, 1st year).
The worst mistake I made was holding some coins that become shitcoins. Especially my earning in bounties few years ago, it had some value before but now it's equivalent to nothing.
A lots of shitcoins happened few years back, some got value back then after being listed but the developers abadoned the project and
ends up nothing.
Those who holds and wait for more developments just wasted the opportunities, lesson learned from that, if there's no real usages then
there's nothing to wait with such kind of token/coin.
Do your DYOR as always there's no sure thing inside this sphere so come and live as it is.
I also remember mining Garlicoin at some point, I don't even remember the reason I did it in the first place. Found the wallet recently containing quite a few coins, which are now completely worthless.
What you have mentioned is absolutely true in my case. These coins used to be worth $2-$3 at some point, I'm not sure on why I kept them, I'd guess that I've completely forgotten about that wallet.
