A few days back I did made a good return after investing in Doge coin. I invested a small amount of 3 figures and in the recent pump was able to get 20X of my investment.

That was a gamble I played while thinking about the US election. Strategically I shouldn't use the word gamble here but risk should be the right word. The risk I took went well.

That doesn't mean it will always go well. Therefore if you plan to become millionaire you will need to take a decision that will be risky while you invest in meme coins. If you can afford that risk and patiently wait for the outcome thay can be both positive and negative then go ahead do it.
