I think that it is better to keep your bitcoins instead of spending them because you make a lot of money by keeping it.
That is what i am doing right now i try my hardest to not buy anything and just wait for the value to reach 10k.

Don't panic sell because a lot of people invest in bitcoin so the value will keep going up as long as there are people investing in it.
And i think that bitcoin will be alive for a lot of years before dying so i think that it is best to invest and not sell.

It is like that for me too because bitcoin now really has become part of my life i look everyday what is happening on the internet with bitcoin.
And i think that bitcoin will stay alive for a long time so you should invest.

I think that everything can be hacked because if you are a good hacker and know what you are doing you can hack anything.
 Like even big companies have been tried to hack by guys and some of the attacks worked.

I think the best time to buy bitcoin is when the value ever in history will drop lower than 2k because then you can make more profit then if it goes down 1k or something. Because then you can't make much money.
