When it comes to Bitcoin, unless you invested in it years ago, you've missed the boat. The same can be said for many of the popular Crypto's out there. Bitcoin has been a bit of a "loser" in the crypto currency community for a long time.
In Australia, Crypto currency is largely null and void with the introduction of the National Payment Platform (NPP). NPP now allows people to make intra-bank transfers in real time, 24/7/365.
Personally, if you're ahead (i.e.: your crypto is worth more than what you originally put in), cash out now, or at least a portion of it so if/when it all comes crashing down, you've lost nothing.
