Litecoin and Ethereum buys and sells are temporarily disabled
I've made about $110k profit this year in crypto on a $21k investment earlier this year, and I think this is all a giant bubble.  I was at my parents' house for Thanksgiving and a commercial with Ron Paul talking about Bitcoin came on, which coincided with around the time it went to $10k, and it hit me really hard that this isn't going to last forever (and probably will hurt sooner rather than later).  I liquidated everything and just entertain myself doing some day trading on GDAX. I don't hodl anymore.The entire thing is absolutely stupid, and isn't going to last forever.  People are way too bullish on it.  People who have no business investing in it are taking on debt to do so, with no clear exit strategy other than "the moon."  A lot of people who don't have any money are going to get absolutely toasted when the pendulum swings the other way.  They're in it to get rich.  They have no idea what blockchains are.  They just think they're buying magic internet money people get rich from.To put a little perspective on how ridiculous this all is: Last night after Coinbase came back from maintenance, there was the (expected) sell-off, so I figured I'd make a quick buck and bought 300 LTC for about $241 each, then sold it a few minutes later for $251 after the instant rebound and went to bed with a nice $3k profit.  I woke up this morning and was astonished to see that LTC was about $380.  This was in the course of about 5 hours.  Had I not sold it last night, I would have made almost $40k.  I'm a little annoyed about that, but again: this is a stupid, irrational bubble that makes absolutely no sense.  It's entirely speculative.I think crypto and blockchain has a future, but it has to solve a few problems first (transaction fees/time and anonymity).  None of the big three currencies do that well enough yet.  This bubble is going to pop soon and I'm worried that a lot of people are going to get impacted badly.
