I'm sure most people have smaller amounts in crypto, it could just be that the people who have so far wanted to comment on this thread are the ones with really high percentages in crypto.
I've for the most part had more than 90% of my money in crypto since late 2017, though it probably slipped under 90% in late 2018 just cuz prices had fallen so much, before I loaded up at the beginning of 2019.
Eventually, like later this decade, I figure I'll want to diversify a little bit into stocks and real estate, so I could imagine by the end of this decade holding like 90% crypto, like 0.2% in cash, ~5% in stocks and ~5% in real estate. But for now I'm perfectly happy being 99.9%/0.1% crypto/fiat.
For me personally I think anything above 80% of your money being invested in the crypto industry is considered dangerous especially for the people who don't have anything set aside at all if one of the worst cases come which is cryptocurrencies going down which all of them will immediately be affected in this situation. But I guess this will really be dependent on each person as maybe there are people who have a bigger risk appetite compared to what I have and has trust that cryptocurrencies will give them bigger gains.
Yeah it just depends on your situation. For me I have no investments or assets (stock, real estate, etc) outside of crypto so it is easier to have almost 100% in crypto. And to have a 6 month emergency fund in the bank only takes 0.5% of my money, which I will save up to over the next few months because having an emergency fund is important. If I'm about to buy a new car or something I'd go over 1% fiat but that would be very temporary just to make the purchase.
This bull run will keep going for a long time, and even if we do get a sizable downturn at some point, I'm still going to be making enough from staking rewards to live off of, so there isn't any reason for me to hold extra money in cash.
However for most people unless you're already rich from crypto yea I agree over 80% means you probably are over-risking yourself cuz the market could be down at some point and you end up needing cash.
People's finances, in order of priority, should be:
1. Source of income
2. Enough in fiat to cover the next month's expenses
3. Emergency fund of 3-6 months in fiat savings account
4. Bitcoin as long term savings
5. Ethereum and optionally some of the major altcoins as investments, ideally some of them are staked coins to generate income. Alternatively you can also use real estate and stocks as investments that generate income but they are just going to grow much slower than good crypto investments.
6. Optionally you can then invest in more risky altcoins outside of the major promising ones, realizing that these are very risky and over the long term you may lose money on these instead of making money, or at the very least have smaller gains than if you had just bought more Bitcoin.
And of course you might own a house to live in which will consume some of your assets.
For me, (1) my source of income is staking from DOT, but I will also stake ADA and ETH soon, plus also I have a trading account that I can cash out from when I need to cover expenses. (2) Right now at 0.1% fiat I only have enough in the bank to cover the next month's expenses. (3) Over the next few months I'll move enough DOT rewards or trading profit into fiat to have 6 months cost of living as an emergency fund in my bank, and I used to have this but just allowed my bank account to drop because I didn't want to sell any crypto right when the bull market was taking off the past few months. (4) I have a ton of Bitcoin as my long term savings. (5) I have DOT, ETH, LINK, ADA as my safer long term crypto investments as they are all both promising and among the top cryptos. (6) I also have gotten BAT, PRE, and RUNE recently as more speculative and risky smaller cap long term investments.
And I don't own a house or any other investments but I will likely eventually buy land for myself, maybe rental properties, and stocks.
