I could remember when Bitcoin was first introduced to me, even other crypto, it was sold as something that will turn me to a billionaire over night but based on my understanding I know aside those get rich quickly scheme that we all know are scam no investment can offer that and I started reading and researching about it.
Bitcoin should be seen from a long term investment angle like 5 to 10yrs to be able to give us that financial freedom we desire
It is very wise of you becoming so inquisitive to learning rather than just depending on how it was first introduced to you. Yes, the person who introduced Bitcoin and some other crypto currencies to you needed to exaggerate a little so as to pick your interest into investing in it.
It is very possible of Bitcoin making you a Billionaire or Millionaire depending on your investment and your strategy applied but in the case of doing it over night not possible as it will take longer time to do so. Having this knowledge about Bitcoin will make you understand the essence of having patience so as not to sell off due to expecting much or when the market becomes highly volatile so you don't panick and sell.
