My strategy is to not deal with any investments that needs deposits to earn. I focus on online jobs and earn bitcoins. Some I convert to cash and some I left in my wallet for hoarding and waiting for a significant increase in the bitcoins monetary value. As of now the results are showing a positive signs that my decision and strategy is effective.
It could be a pretty good strategy too. Freelancing could be an excellent way of generating extra income, and if done right you could save at least 10% of your earnings for altcoins and the other 40% for BTC. Then the remaining percentage would be used for savings or spending on commodities like Gold or Silver. There are many ways to invest but those who prove to give long term success are worth it. It's always good to minimize the risks. Just my opinion.
