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 prices in the market is always depending on the demand and supply so you can wait for the prices to decrease even more before selling your coins, dumping of prices in the market means you need to invest even more in order to earn a huge amount of profit.
Investing with a lot of it will make us a chance to get big profits too, but the risk will also get bigger. This is a very common thing in the world of the stock market, investing at risk will certainly make us can get better results than just when playing safe. Playing safe will not get too much money too, make sure that we always make good decisions.
