all you have to do is write off the money you've made for up to 4 years.

I'm 75 years old and I'm still learning, but I didn't read the forum requirements in English. 🥸
🤔 This is full of bait for "carps".
I don't feel prepared enough to give advice and share my wisdom.😉
🧐 I'm only sharing my experience with "trial and error" and everyone can judge for themselves:
In 2012 I "mined" 5 BTC at a price of 10$ for 1 BTC.
In 2013 I sold them at a price of 200$ for BTC 🤑
I lay down for 10 years at 20x "profit"😌
🥱 I "woke up" in 2021 at 69k for 1 BTC!
🤓 I found in the "wallet" with BTC - a few forgotten "cents" and multiplied them at a price of about 40k.
🧐 I sold part with a small profit at 60k.
I ordered to sell 1/2 when it reached 90k and again 🥱 until the sale woke me up, and my son (who could have paid off his mortgage with the 5 BTC sold) cut off - DO NOT sell!
🤔 I stopped, looked around, listened and diversified here - as much as I can lose painlessly, because I have invested the others in 4 other places.
🤓 By the way, part of the investment here is from a gold coin that I bought for 3k and (after 2 years) sold for 5k
👉 On the graphs in the pictures - the green markers are purchases, and the red ones are sales.
💭 Conclusion - waiting is the mother, especially for those from the future.😎
For the rest - gambling.
