Long term investment and exit strategy

I've been interested in the crypto space for the last few years, and thanks to a fortunate mixture of timing and ponderate investments, I managed to gather a decent portfolio of ETH, BTC, DOT and SHIB where everything is in the green and, at this very moment, up for around 90% of my initial investment. Roughly 70% of my crypto is ETH, 15% is staked DOT with roughly 0.35 return pet day, the rest is BTC and SHIB. This is not exactly life-changing money, but still a considerable asset I was thinking using to buy a house – or at least, to pay for part of the advancement that won't be covered by the mortgage. Now, I am torn. I might be able to get the money I need for the house elsewhere, but using my crypto would just make everything so much easier and faster. On the other hand, I'm fairly confident in the projects I invested in, and would happily keep those crypto there for the next 10 years.

How are you guys handling your invested money, and what is your medium- to long term exit strategy?
