I think that is not going to be enough if you are going to depend on one source of income. But trading is already a good way to become rich in bitcoin.

But don't forget that not all the time you are going to get good profit with bitcoin trading or alt coin trading. I want to suggest that while you are in trading.

It is better if you are going to have some funds for holding.

Building a blog is good enough but it will need a good traffic to get ppc adsense account. But I never know that some publishers were recieved payment with bitcoin. I think holding bitcoin in a long terms is the effective way to get rich with bitcoin becouse I read some post in this forum that explain about bitcoin price rise. But how long until it is happen?? . For me join the signature campaigne is the fastest way to get rich with bitcoin now. Probably there is another way that better than just joining signature campaigne, but I do not know.

Building a blog is definitely a hard thing to do at first. But when you reach a 5K steady audience, it will start to grow even if you don't promote it that much.

Signature campaign isn't the quickest way to get rich in Bitcoin. The quickest way is gambling but it's also riskiest. Well, plenty of rich people out there got rich because of winning a bet in gambling but that doesn't mean that it'll happen to you too. Signature campaign is the one of the fastest and safest way of earning Bitcoins.

You can earn a lot of money in new altcoins too but it's still a gamble because most altcoins stop updating when they reach a certain amount of money. They just become a scam coin.

If I have of money, I want to buy bitcoin
and hold them for the longterm and I sell it when prices increased.

That's almost you are saying that when we are just earning bitcoin we are nearing hopeless to become rich of it. I think that's not the right way, you would look like a person who just accept who he is now and no dreams for the future. There should always be a plan, for sure in your life you are also dreaming of a good life, and I think you just have to realize those.

i want to earn bitcoins online from different tasks and I will earn from my blog from the ad banners from there etc and when I will have a large number of bitcoins then I will start a business with that.

My plan to get rich with bitcoin is to save up alot of bitcoin and invest alot of fiat in bitcoin. Everyone believes bitcoin prices will raise alot, I am also waiting for that moment.
When it happens I might sell my coin and go back to fiat.

Yeah money attracts money, if you are starting from zero and planning to get rich in bitcoins then it may take long time and there is no guarantee that you will become rich with it.

It is hard to get rich if your only source is bitcoin but it will helps to get you rich if you have bitcoin exchange in your area because business is the thing that people make people stable in their life or to be rich in the future.

Yes and  if we want to become rich with bitcoin then  we should try to collect as much bitcoins as possible either by buying or by earning it, if price reaches on the top in future then more coins will give you more money.
