for now, I can do just constantly collect bitcoin of some way to follow the signature campaign, trading and faucet. after I had bitcoin by the number of that much, I will open a business
At this stage our main focus should be to collect as many coins as possible without thinking that it can make us rich or not, and if we manage to have high amount of coins and if price reaches to the moon then you will achieve your goal of getting rich with it.
To be honest, "collecting as much bitcoin as I can" will not actually work unless you earn 0.5BTC a in week or maybe more. Just calculate everything. I think most of us are collecting bitcoins from signature campaign, being in signature campaign would give you 1BTC in less than a year depending on your rank, the campaign you're in, and the number of posts that you do.
1BTC is already a good amount of money but, it's not enough to make you rich. Even if Bitcoins fly high to the moon like 1000$ each or 2000$ each, you're still not rich because the amount of your Bitcoins isn't that much. The only ones that will actually get rich in Bitcoin in the future are those people that are already earning a good amount of Bitcoins. Not to offend you, guys, but I'm just being realistic.
