I have an AmeriTrade account strictly for gambling. Every dollar I throw in there is like tossing the cash over a dumpster fire in an attempt to have it land in soil perfectly fertilized for money trees.
In 2014 I was slowly buying up pot stocks as legalization expanded. Some made THC or CBD products, others leased small-scale farming equipment, another was using kenaf crops to make a HazMat cleanup product. All went to heck.
Right now I'm taking $300 of my teaching paychecks ($4,800) to buy shares of Fannie Mae on the idea that eventually it will go up to something like $5.00 or $25.00 or [pinky to corner of mouth] $1,000,000.
While doing this, I'll invest about $30,000 into long-term retirement, pay my mortgage down by about $18,000, and start a Ph.D so I could move into full-time teaching, making about a 10:1 ratio of smart:dumb ideas.
So, THE ADVICE: If the downside won't hurt you, why not? Lastly, buying single stocks was something my dad got me into. Perhaps you have something like that, too, where having this account is something you did with someone you love - maybe someone who is not around anymore. Now, my dad wasn't a dumbass like I am, but if I told him about it, he'd just wish me the best and maybe let me pick up the tab at the bagel shop if it all worked out.
