Currently holding seems the best way to earn something with bitcoin.
Trading is risky and you can lose
Cloud mining is dead and you will lose too

yes because bitcoin prices are rising sharply I think that we should not miss this opportunity to buy a lot bitcoin and you will get a profit in short-term.

Yes it can also be done by continuing to collect bitcoin.
That if we want to be rich also have to try hard.

Yes true it can make us gain a small advantage and I often do that.
But to be rich, we must strive to be able to collect a lot of bitcoin.

I am doing the same. I try my best to accumulate the bitcoin. After I get it, I will hold it in my wallet.

If you want profits from holding it, try maybe holding it for maybe a few years and then sell it. Or maybe you could just go trading and always hit and buy when it is the "low" and sell when it nears the 12hr high.
That's how I do my trade and earn profits, although not so much because I wait for too long but it's decent.

my plan to be rich in bitcoin is i will invest my money from my real work and stop my real work and i will focus on growing bitcoins and buy some bitcoin miner devices and do other business in internet world 

Dude why you will quit your real work, if you can focus to them both. Working on your real work and working with bitcoin.
You don't have to quit if you can just properly manage your time, It's hard to find a real job, but if that's your plan. Of course, you know
what you are doing and you will sustain your needs from it.

Okay that is a good idea but I will agree with boyptc. Think about it again. Think about the future. Is doing this choice will be good until 5 years or more. Will I get bored someday with just staying at home doing this? Get some question for yourself before taking a leap.

That's a joke I think or probably he/she is not paying his bills to think like that or a kid. We should not be lured by this things that is happening to the price and just easily quit our jobs, that's not easy to go on full time with bitcoin and get rich. A hard work in real life is still the key, and invest some of your savings to bitcoin to earn extra or an average income from it.
