It's a good time to buy as long as the price is under $1k ...
Even the price hit more than $1000. It will still be a good time to buy since the current user of bitcoin is still few and expect the price to go higher which will result to a 5-digit value of bitcoin.
That is true. If you think the bitcoin will rise a lot in the future, say in 50 years, then it is good time to buy now.
I am also long term minded, but looking 50 years ahead is not possible/realistic as we don't even know whether or not Bitcoin is still existing by that time.
