At the current state, I think it's now easier to build a time machine, to go back in 2009, rather than hoping to become a millionaire buying BTC at this time.
well everything is possible to be honest, also if you built a time machine you wouldnt need to use it because you would be rich
All of that makes no sense, time machine is a machine that is only used to give motivation to the scientists or professors to further in recognizing various event or something that exists in the world. So if time machine will never exist and it will only happen when there is someone that is sent by God to deliver the complete help
If you think of time machine, you will never be rich because instead of thinking for the future and focus on the present you give more time to past events that cannot be change anymore, we should be more realistic so our approach in becoming rich are more holistic.
