Aiiiiii that's a lot of money. This is what I'd do:
Take half,eh,and buy a website. A website that earns money.
125,000 = ~ $1,560
That's good money. But the trick is to find a site that isn't complicated to run,and one which has a nice passive income. It may not be 25,000 at the start but with websites there's always room to grow.
And as I said you buy one where there is passive income. So you can take some time to understand it while it is earning. Improve it and you earn higher.
Then,if it earns higher...why not sell it? You can make good profit this way. My friend once bought a site for $400 and sold it for $2000 three months later. After we spruced it up a bit.
Anyway,that's just me. Think about it.
