I just found this when i tried to search more info about bitcoin earlier this day,
https://www.investopedia.com/terms/s/sell-in-may-and-go-away.aspWhat Is "Sell in May and Go Away"?
"Sell in May and go away" is a well-known financial-world adage. It is based on the historical underperformance of some stocks in the "summery" six-month period commencing in May and ending in October, compared to the "wintery" six-month period from November to April. If an investor follows the this strategy, they would divest their equity holdings in May (or at least, the late spring) and invest again in November (or the mid-autumn).
I know that thread is talking about return of stock, not cryptocurrency, then i will show you this (bitcoin return on every month)

From this pic, we can take a conclusion if after May - Oct, bitcoin price seems more likely in "Red" instead of "Green". What do you think? Is this coincidence?
Vote the poll & give your reason.
Note : You can't edit your poll once it submitted
I put my vote on the pool in "don't care" because it is too reasonable. I don't think you had to decide now but do what your logical thinking tells you. And it will always work.
Let's just say that you didn't sell your assets this month and then the decreases came, you only had to keep those bitcoins and in the next first-second quarter next year and you will still recover and possibly gain more.
If you really needed finance now, then sell the half, or move to Bitcoin. You don't really need to care as you have it all now. I really don't think that the poll helped you as I can tell you've been very good at handling your assets. You'll never get where you are right now if you don't.
My opinion is based on the data you have here. It is simple. If its not the time this year, try it again next year. Principle will still be the same though.
