For whatever reason you have to sell, having a strategy set up in advance is never a bad thing. Trying to match the top is far more difficult than predicting the bottom (e.g. 200W MA) in my opinion. For that reason, a sell ladder can be a good strategy. It's automatic and it won't cause you stress trying to match the exact top.
I personally sold some coins between $30-40k to reinvest in real-estate. I could have held them longer for more fiat gains, but I had a strategy set up a long time ago and I held on to it. No regrets.
Right now I have no need for more fiat, so I have no further plans to sell anything.
I have had this same plan personally. I could have been a billionaire if I held on to all of my coins. Sounds tragic but I am just as happy being a decamillionaire

. On one hand, you never know for sure what it may reach, on the other, you want some gains in-between. Make a plan that you can accept the consequences of whichever way it goes.
