Sounds like you did really well though. Do you plan to take some gains off the table? Seems risky to keep that large of an amount in crypto.
We'll see what this year brings. My plan was to wait until 2020 before thinking about doing anything. If the prices become ludicrous this year then I may look into it and take out a percentage, though I think I can't be bothered as I've set on fire everything the tax man has sent me for the last two decades, but other than that I'm staying put.
What are your own plans?
My plan is to stay out of crypto in the short term. I think this bubble cycle is over and it may be a couple years before seeing new all time highs. I also have doubts about bitcoin specifically because of its scalability/transaction/technical issues. Right now I'm more in stocks/cash and plan on buying a house soon so I'm trying to keep risk very low for the next few months. Once I have a house and if crypto declines more, I might consider a few alt coins for a small speculative investment. I think IOTA looks interesting but I'd have to do more research.
