I'll bite. I'm not a professional financial advisor, just an enthusiast. This comment is for entertainment purposes only.<p>Step 1: get general investment knowledge first. You need to know your alternatives.<p>Step 2: invest in Bitcoin or Ethereum by using appropriate bankroll management. Also see mikewarot his comment on the dollar cost averaging strategy as one way of appropriate bankroll management. For conservative investors I recommend 1%. For super hyper aggressive investors that want to yolo in all their money (including the money of their parents and grandparents) and expect to be rich by Sunday, I recommend 10%, NO MORE (feel free to ignore the shouting if you don't fall into this category, if you do, then reread my recommendation including the shouting 10 more times).<p>Step 3: come back in 5 years<p>As for exchanges, I'm most happy with Coinbase. I've used: Kraken, Binance, Poloniex, Crypto.com, Bitfinex, Bittrex and a few I don't remember. Most of them I don't trust. I'm still in doubt about Binance and Crypto.com. Binance: because it's unregulated. Crypto.com: because they either have unexpected charges that they don't tell you about or they have <i>very inefficient</i> spreads.<p>Todo step 1:<p>A. Read the Intelligent Investor. Understand it. Most of the value investment material is relevant during market crashes, and a lot of timeless knowledge is in there. Learn about the difference between trading and investing, margin of safety, etc.<p>B. YouTube channels to watch: The Plain Bagel, Patrick Boyle.<p>C. Understand: CAPE and Shiller's work in general, ETF investing (check Bogleheads.org) and Fama's efficient market hypothesis. Shout out also to the Kelly Criterion.<p>D. Whatever you do, do not learn anything about trading. And if you do, do not learn anything about technical analysis and assume you need <i>at least</i> a master degree in statistics and probability theory.<p>You need to know if other assets are actually a better investment for you. I'm currently learning about real estate and options as both have financial leverage factors in them. Though, I don't think you need to know about them as an alternative as they require you "getting into the investment and/or trading rabbit hole". The above stuff, while it takes about 50 hours, that's it.
