Miners consume electricity and other resources too while i guess this may inefficient now however trading is more lucrative these days to make more money within no time. I also noticed that many brokers like hfm now allowing btc cfd trading.
Scalpers only wait for the right time to make their profits as the market moves sharply including volatility on news release. This broker allows trading during the news release.
The newcommers lose money because they come with a mindset of becoming rich right over the night after joining this industry. They do not cater trading as a business and treat it like casino to push buttons to make money.
I see with binance and coinbase evolution, there are many brokers like lmfx who started offering spot digital currency trading and some like hfm also offer bitcoin cfd trading too.
I have assumed so far that there is nothing free in this world however the only way to make money is to learn trading and invest in it which can yield guaranteed results rather than investing money or time on any other venture.
Education is a must have in trading and i also have noticed that most of the brokers like hfm etc are investing in traders' educational awareness programs as well.
The statistics on their website has good number of traders with much handsome trading results which shows traders interests in demo trading tournaments in my opinion.
