Gambling might give you huge returns but there is always a high probability of loosing than winning.
Investing in promising altcoins is also a good idea but I would you to do what you are currently doing. Trade in fiat and altcoins. It is a slow but sure growth if you have a proper strategy. As you capital increases your profit will also increase.
Nah Don't bother trying to earn on gambling its not a good source of income more like a good money eating machine. Just stick
with their advice to try trading, Unlike signature campaigns which the only risks are your time and effort going to be waste if
didn't get paid, In trading the risks are much bigger because you will invest your money to it. It is a good source because you
can earn a much bigger amounts than your eanings on signature campaign but it depends on your strategy and your capital.
Trading is not that option that has bigger risk since you are the one who will manage your money and it is up to you on how you will grow your bitcoin. In trading, the sky is the only limit and the only pilot that will help you to reach those skies is the only you. So invest in your self and learn a lot of things start with basics then after you understand how the market works and how the trading works then you can start investing your capital whether it is fiat or bitcoin to an exchanger's site then start your trading journey. Don't forget to learn from your mistakes and make them as a basis on your future trading activities.
