The best way to start earning in crypto is to learn as much as you can about crypto and start with signature bounty and later go for various bounty campaigns.

Good trading, a lot of researching, participating in as many airdrops as possible, be part of communities and all that.

We all know these methods but the main thing for the newcomer to adopt any of these method is to grasp complete knowledge of any of these method. Once we know have full knowledge of these methods, then for sure they can be a real profitable but going after them without getting any knowledge will make you only lose money and nothing else.

There are many ways to make money with crypto currency such as providing services, selling goods, trading, or just holding your bitcoin to make profits and gambling but I do not recommend it. I think you should read daily news related to crypto currency to understand it better and before you start trading.

There are several ways to be able to earn profit/make money in crytpcurrency such as selling and holding bitcoin. But I preferred holding. Also by investing in a long term basis, joining campaigns and ithers.

To make Money in the long-term, it's really a matter of finding undervalued coins that have strong fundamentals which have the potential to increase significantly over a long period of time. By doing that initial research, you set yourself up in a way that you don't have to worry about the volatility of the market because you can feel confident that it will recover and be worth even more afterwards.

Trading crypto currencies is a brilliant way to make money, however, it isn't as simple as many portray it to be. Each type of currency having several different underlying factors which affect it.

Bitcoin has certainly been the most successful one, but that's mainly because of its wide acceptance. Especially if you go on to shop anything out on the dark web, you'll wonder if bitcoin is greater than USD.

Firstly, you must be a great forex trader, learn the technical analysis involved in trading forex and using those you must find a strategy by back testing various indicators on the crypto currencies charts.

Despite having enormous passion towards trading, I do not trade cryptos due to a constant fear of unreliable crashes.

Stick to one, keep observing the chart and using simple support and resistances too, you should be able to make some good money.
