Do any of you guys own any cryptocurrencies? Either bitcoin, litecoin, or another alt-coin? It's got my attention lately since bitcoin has been up so much lately (nearing $12k/coin). It could be a bubble, or cryptocurrencies could be the future.
The one that has by interest lately is Stellar Lumens (XLM). (Full disclosure, I own some)
It seems like bitcoin, while sort of the "gold standard" of crypto has problems that some other cryptos like XLM don't: Slow networks, and expensive transaction fees and 3-5 second confirmations. I can see a lot of uses for irreversible, low-fee, near-instant transactions, particularly on the Internet.
What are your thoughts? Bubble or the future? What crypto's do you own, if any?
