I have Sia and Monero for long hold. I dont know what gonna happened in this year. Maybe we gonna see rise, but more likely in next year.
I hold it because I like team and idea of project.
I am long with bitcoin and Eth. The reasons is both are top in cryptocurrencies list. Also since eth is alt coin and it can be useful in trade where bitcoin is good for long term invest i can hold my bitcoin for years.
