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.
The best time to invest is during the lowest price of bitcoin and other altcoins. Its pretty sure to double your I nvestment when the price goes up. In business the best time is when you have all the capital, product, location, manpower and if you are ready to venture into business. It is important that you are physically, emotionally and financially ready before going into business.
