In my opinion, the opportunity to get rich through bitcoin is still wide open, because now the price of bitvcin is still cheap, and later the price will rise even higher
Price does not matter here (however, do you think that Bitcoin is really cheap?). You can find out the ways to make money on BTC always. Trade, invest, take part in Bounties. Try again and again, and finally, you will be wealthy.
Taking part on bounties to make that mentioned people will make wealthy this chance is rare. But the person can be wealthy if the person can invest on bitcoin because the price of bitcoin will increase a lot from the current price.
