Those who can't afford potential looses and are not comfortable with the market volatility should just stay away from bitcoin investment, for the game in bitcoin investment is not for them
These ones are the uniformed. If they can't invest what they can afford to lose, then they can't even afford to hold. The market volatility in the Bitcoin will.give a heart attack they couldn't imagine.
Those seeking for short term profits should just stay way from bitcoin investment, for Bitcoin investment doesn't give short term profits, where those category of people belong is cryptocurrency trading and not bitcoin investment.
I think these ones are looking to others who took profit and they think that if they invest a little in few months it will 4x and they'll take profits too. What they don't know is missing is that taking profit may take years before you can comfortably take profit.
