You still have a chance to be a millionaire through Bitcoin... If you have the guts to invest a big amount of money in cryptocurrency however even if you invest a big amount of money you can't still be a millionaire if you don't have enough or proper knowledge about the market or trading.
You can gain profit from the volatile market take the guts on buying on the bearish market and earn a lot in bullish market however the risk of investing to a volatile industry is high so you should know the considerations you might get in investing to cryptocurrency industry.
I think the problem of loss or loss not only occurs in the cryptocurrency market but also in the stock market, real estate or other investment assets. Although the mayor of cryptocurrencies is unpredictable and unstable, the loss or success is largely due to you, if you want to be rich, then lose your safety, nobody succeeds in just one night, must undergo through the difficult road to find success, the cryptocurrency market is a new and potential market, if you spend enough time to learn about knowledge, gain experience through transactions, then success is yours.
