What's the best way to invest? Wall St won't tell you the secret, but here it is: don't. Find a good money market fund as your base, and clip coupons by building a high quality relatively short duration bond ladder. It's essentially risk free, and it has beaten the market for over a decade now. Sleep well, save well, focus on your career, and enjoy your life -- and though you may not believe me, I guarantee you'll beat 95% of all investors in the long run, and you won't have to pay any "advisors" a nickel.
For me, trading in digital currency, the best and effective way to do is to just buy low and sell high and you can never go wrong about it. When you buy low, just hold it for a long term investment and keep yourself updated so that you will have ideas on what to do and plans to execute. Once the price increased, just sell it if you are satisfied with your income.
