Well if you have 100 bitcoins in your wallet and then you can wait for price hikes in order to be rich but those getting bitcoins from micro sources in bits are just not being realistic with themselves. So go ahead you can dream but be realistic.
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.
