If you sell your Bitcoin and have to pay taxes, then you’ve lost your Bitcoin to whoever bought it. So long as you live within your means (which is what a Bitcoin based economy teaches us), wouldn’t it make more sense to keep your Bitcoin and borrow the money?
No, it wouldn't. It doesn't actually.
Because in your argument you are obviating the increased purchasing power of Bitcoin, with which it is worth selling to enjoy the benefits while maintaining or even increasing purchasing power.
Stop listening to the snake oil salesman Saylor.
Those who sold $1,000,000 worth of Bitcoin for $10 in 2011 have lost about 25% of that value. If they borrowed smaller amounts as they needed it (with the means of paying off the loan, and the ability to sell some Bitcoin if times got tough), they would have over $2 billion in Bitcoin.
You are cheating yourself.
Like selling $1M for $10? What the **** are you talking about?
It will always be better to sell small pieces than borrow because in order to borrow you will have to deposit at least twice as much, giving up your private keys, and with the volatility of Bitcoin, you will soon receive a margin call.
Why would you have to hand over your Bitcoin? Perhaps you do now, but I am talking about the future when Bitcoin is more established. You don’t have to move out of your house when you use it as collateral. You only have to prove that you possess the asset that you’re using.
Here we are talking about realities, not what you imagine. You have to hand over your Bitcoin in order to borrow.
