I've been stockpiling *all* of the Bitcoins I've accumulated during the about nine months I've been in Signature Campaigns for use in creating Lightning Network Channels. ~ I guess HODLing for a year or two is my XMAS-Crypto resolution.
LN is still highly experimental, so I wouldn't feel safe holding a lot of funds in there. I consider HODLing more of a cold storage kinda thing than using hot wallets or even active open channels.
Just last week I found a really nice way to use my LN funds. I use it to buy coupons to buy what I need. It's a rediculous system with several additional middlemen, but it saves the ~0.2 m
BTC "network fee" charged by BitPay,
and my own on-chain transaction fee. For a small payment (around $20), I now pay a total of around $1 in fees, instead of $5 or more.
If I can wish for someone else's new year's resolution: I hope shops that now accept Bitcoin start accepting Bitcoin LN this year, so I can cut out multiple middlemen.
