Your return in investments are commensurate to your earnings,you can't expect to invest 100$ and earn more than someone who put in a 5000$

It's just basically easy to figure out,the major constraints in investing is limited capital,and so since the rich have enough capital to throw about,definitely they'll earn higher than those with far less capital

Smartness,patience and less greediness are vital tools in trading/investing
But the major determinant is investment capital,without it, the aforementioned tools are useless

Of course not only the rich people can make profit. Poor or less financialy stable people can make money trough Bitcoin. For an example I have made some decent amount of money from pretty much nothing because I didn't have the money to buy and trade Bitcoins. But it is also true that rich people make a very larger profit because they have more money to invest. Only the intelligent and smart can make more profit than them.

Bitcoin as a currency and payment system can be used by all the people. Also, for earning money there are many people form different classes involved in cryptocurrencies. There is no need to be rich.
Some can afford to buy 100 bitcoins and some can afford to buy 0.01. All people can invest and all people can earn money. All people can trade and all can work for cryptocurrencies. I am sure many people here in the forum are in the lower middle class.

I think even rich people can lose a lot of money on Bitcoin investments.

This is a very dangerous business and a very small circle of people earn from investing in Bitcoin

The point is that $100 invested has the capacity to increase much faster than other areas of business. Like for example, during the last December trade, some small traders experienced high financial growth on their investment.

Rich and poor have right to make benefits in bitcoin
Bitcoin is for all people niot only for the rich people
Bitcoin created to help people to grab the opportunity given by the new technology

Indeed it will take a lot of time for people to implement it to different things. Different spheres will try to implement it to use cases which are possible, but also people will be worried about the goverment which always control money circulation and if it's not allowed you can get a fine, but earining from it will be possible later for all social levels

If Bitcoin is only for rich, I can not join it as I 'm not rich .Bitcoin is  for everyone who have ambitious for being rich with a little money , patience , good understanding, calm..

assuming you are right, that many people become poor with bitcoin, Eric Finman, his age is 19 years old. youngster who is rich with bitcoin.

his estimated wealth is $ 6 million. he was only given $ 1,000 by his grandmother, and then he used to buy bitcoin, when bitcoin price was still very cheap.

not only rich people can get profit from bitcoin
people with little money can do it too
especially if they use bitcoin to invest in altcoin
of course you have to do some research before investing in altcoin
