Seems like you got most of your bitcoin in the time frame I got most of mine. I think out of my cryptocurrency, bitcoin is 95% and it’s on a hardware wallet. I stopped most of my buying, however, at the end of 2016. I ran a full node in 2016 but I had technical difficulties with how I set up my virtual machine. I am better educated now. I have a full node running on a raspberry pi and I am just getting started with lightning on my desktop pc. It’s working on syncing to the testnet chain. I will work with lightning once I get a full testnet sync. The more I study bitcoin, the more I like it. Its going to have the best use cases by the end of 2019. There are currently 2000 alts. Next year lots of them will be delisted from exchanges.
I do have Zap but since most of my time is on a computer at work behind an enterprise level firewall . . . well, let's just say I can't experiment with it.
As to the alts, I am so sick of seeing just how much stupid people will buy into.
