I think it's a great time to buy altcoins before Bitcoin's halving begins on May 12, 2020. Prices will skyrocket like never before, because Bitcoin's block reward will be cut by half. The hype will be there at least for a year or two, until everything goes back to normal. If you've managed to invest into the most prominent cryptocurrencies on the market (such as Litecoin, Ethereum, Monero, etc...) you'll be able to experience massive gains in the short term. I'd suggest that you sell some coins during the bull market run in exchange for a stablecoin of your choice (or even Fiat) to preserve your investment. Then, you can buy the same cryptocurrencies back again with the stablecoin or Fiat when prices go all the way down the drain. Repeat the process after every halving, and you might be able to maintain a steady financial life.

Of course, crypto is an extremely risky investment. Prices are very volatile (unstable) across the market leading you to quick losses if you don't know what you're doing. It's always best to perform your own research into the altcoin you're willing to invest, just to be safe. Old altcoins are to be trusted since they've been on the industry for a very long time. They have dedicated development teams, and real use cases for the mainstream world. However, not every altcoin is like this (especially new ones). There are a lot of Bitcoin copies (Bitcoin-based forks) which have no utility in the mainstream world. They're simply quick money grabs by their developers, becoming useless coins in the long run. As long as you buy the right altcoins, nothing should go wrong. Just my opinion
