Depends on your comfort level.
Diversifying gets you 70k upside, or 20k if everything tanks, a nice little hedge for the long term investor that likes to not look at his computer at midnight.
letting it ride gets you 400k upside or 0 if your choice tanks, the choice of someone that may be tired of the long march towards his age 65, 1.2 million savings target.
I have some existing traditional investments that have got me exactly what you would expect over the last ten years. Average returns and an average progress towards retirement.
But in the past six months I am all in with new investment dollars into crypto. I am not going to stand by like I did with Apple, Netflix, Google and other great investments, and watch them all do great in my 2% of ownership diversified holding.
I am riding Bitcoin or other Cryptos (DOGE until tehy go to the moon or until the go to zero, one or the other. In two years, I will either be in the same place I am now, which is 20 years from retirement, or my life will be totally different. I do not see another opportunity like Bitcoin, and haven't as long as I can remember.
Diversification is for those that are planning to retire when they are 65, I have never met a single average guy that paid for their house in a year with a diversification strategy. Whether it was a business they built, or an investment strategy they chased, they were all in. Just saying.
I love it. I share this enthusiasm for the great opportunity we have before us.
OP you will have to decide for yourself.
