$ 1 million is a good capital to buy coins, when the market is red like yesterday it becomes a good opportunity to buy, with $ 1 million I will give 80% to buy 5 main coins that I will use for staking, and these coins are CAKE , BUSD, Uniswap, MATIC and BNB.
That is a great approach, to both have money that is coming in constantly, and to also have the coins themselves. If you invest in any coin ever, it may go up or down, but if you invest into coins that you could stake, you have that AND you have passive income as well.
If you invest into bitcoin, you will not be taking advantage of the mining income, that is for miners, but if you invest into something like cake then you could make a profit for just holding it. Considering they could give anything between 10% to 100% (cake restaking has nearly 90%) then we could assume that on average you could make at least 20% yearly income.
From 1 million, that is 200k, even if we say 180k, that is 15k per month. So, not only you will make 15k per month, but also price could go up and that means your passive income will go up as well, so you will basically live forever with that money without ever needing to anything else. Only possible problem would be if these coins go down in price a lot and stay there and never go back up.
