You are probably better off saving your money until you have 5K or better to invest in higher quality stocks. If that 1K is important to you, then don't invest it if you are going to be upset if it is gone in a month.
But, if you do lose the 1K, consider it the price of Tuition for learning something new about the markets. You might learn more from trading (winning or losing ) that 1K than sitting in class for a semester studying 2,3 classes on Business.
Cryptos seem to be heating up again. BTC was $9,000 3,4 days ago and now it is $11,000.
I am not a major fan of them, but if enough people are, then the price will rise,
(Tulips, Beanie Babies, Paintings by Thomas Kinkade). A rising tide raises all boats. If you bought some Ripple (XRP), at .43, you are less likely to lose all your money like you would do if you bought a penny stock.
I own a few hundred shares in BLOZF. It's a Canadian company that is doing research on breathalyzers for marijuana. Currently, there is nothing that will detect marijuana, similar to the way we can detect alcohol.
It is about .95 and it has been there for two years. But, if they ever figure it out and get it licensed; they will be the only ones in the world with the product. A breathalyzer for alcohol can cost $10K and every community has dozens or thousands. Multiply that by all the cities and counties across North America, Europe etc...and there is a lot of $$$$ potential. But, it's still a work in progress.
They have a legitimate product with unlimited potential if it is successful.
So, the risk is worth the potential reward for me. Most penny stocks aren't worth the risk though.
Good Luck
