Tripling an investment with zero risk over one year is absolutely not guaranteed and definitely risky, don't let people tell you otherwise. Especially in this market.
If tripling money is easy, everybody would be wealthy af: you'd simply save up $1k and start tripling it!
$3k > $9k > $81k > $240k > $700k > $2 mil > $6 mil.
If something is easy it should be trivial to be able to do it six times. However, in the real world, it's not.
Many people have a saved $50k, so why don't they simply triple it 4 times this year: $50k > $150k > $450k > $1.35 mil > $4+ mil?
Most reliable way overtime would be something like an index fund. Fidelity, Vanguard, etc. offer them.
Next risky would be something like a "stonk" or pennystock on Robinhood. Keep in mind that shyt is a casino. Nobody is really trying to analyze any company/stock for their overall worth.
Similarly, the most risky is cryptocurrency. There is zero use case, it's a ponzi scheme: there are no real world products like computers, tv's, etc. holding the price up and it can 100% go to zero. Basically a bunch of people shill something, then pump and dump it. Unfortunately, you can lose your $5k in as little as a few minutes. If it his though you can get multiple times your return. However, they rarely hit and the market is looking bad. Many people who got wealthy off crypto have already done it years ago.
Stonks/crypto are pretty much the same crowd. Bunch of loudmouth libertarian-types trying to make you experience FOMO to put your money in so they can rug pull.
