I bought a bunch of doge one time and the bottom was dropping out of the market, right after I bought all the shares. Being a newcomer I got a little nervous and sold my stocks, putting me at a $300 loss! Rule of thumb, if the stock has a somewhat solid history of going up and down, and you get caught with your pants down buying high, just hold on to it until you at least get close, then when it bottoms out again buy it up and make up for losses if you suffered such. Otherwise just keep your eyes on the fluctuations before you settle in and buy.
