A lot of cryptocurrencies have been created throughout time.
I personally have not held onto any old or even dead blockchains.
But I am working on a new project focused on old blockchains and with the attempt of reviving them.
I wanna ask what everyone here is holding onto.
I am mainly interested in coins from 2014 and older, but anything you deem "old" is welcome!

I might hit you up if I find your coin interesting

One of my new picks is Leacoin because of its age and simple configuration.
From what I understand about the blockchain generation is already in the 3.0 generation with better speed and proof-of-work, my advice in terms of technology is better to at least keep up with the growth or be more advanced than the current generation. Looking at cryptocurrency, the old coin that I hold is definitely bitcoin, I'm sure users here mostly hold bitcoin.
