I took all my investment back when BTC hits 8000USD.
I knew it may go even higher, but I'm happy to ride the increase without worry that it may go to 0 tomorrow.
Next major point I will cash out may be 20k USD, to take some money out, pay the tax and start a business, to replace my daily job.
Then... I will hold the rest of my BTC till it hits 50k
This is a good strategy to do. Waiting to bitcoin increase and reach the goal that you made to cash out some bitcoin. I always do the same, i don't like so much to convert my bitcoin and withdraw them, because i know that i will be the looser in this case, Sometimes i didn't touch my monthly income of btc, and somtimes i just spend around 10 to 20% of it in a month depending on the price.I knew it may go even higher, but I'm happy to ride the increase without worry that it may go to 0 tomorrow.
