In my opinion you should invest in many projects and lots of money, trade with an average amount and a little to ensure safety. investing in so many things will ensure that if you have one or two currencies devalued, the other currencies still rise and make a profit.

Due to the OP message, i don't see the manner of invest in many projects as a good idea because multiple projects investment require a lot of knowledge with the inclusion of time to supervise the project invested and i believe the best option the OP have is to start a long trading with bitcoin.
