If I have that amount of bitcoin I'm already a rich guy. And it's not that bad to dream about becoming rich in bitcoin but that's what you need to do, yes we need to be realistic and I'm dreaming that when I was able to hold 20 bitcoin that will make my life on a financial freedom. I want to have my own home and car together with my family.
If we start working hard on it then we can surely have 100 bitcoins in our wallet in future and earning 100 btc is possible with trading no doubt it will also involve huge risk of investing huge amount of money but if you have good knowledge and have extra ordinary skills then you can earn that amount in long term and once you have that amount in your wallet no one can stop you from becoming rich.
I'm calculating it that earning 100 bitcoins at the moment is my one dream in bitcoin industry but I guess I will be hitting that without any specific year or time range. But the only thing that is coming to my mind is that, I will be having a difficult time to invest and earn with that amount very soon but still there's nothing impossible if you believe.
