I'm wondering what should be the right way here. Taking the doorframe trim for £10K.

I see there could be like 3 options: 1) hide wealth / do not spend this money; 2) distribute to economy / i.e. pay a tradesman to curve the frame; 3) donate money to a fund or throw from a balcony to the crowd.

It doesn't seem that 1 cold be helpful to anyone. We see 2 in those examples, but it seem you imply that it's not the best way. So we have the only the 3rd option left, with donations. Is that what is considered as the best option? Is it sustainable in a long term?

Throwing from balconies doesn't work. Pavel Durov tried it in 2012, it quickly turned into a brawl under the balcony. So the one above got bad reputation, being called out by the media for making PR stunts in bad taste, and the ones below might have even had negative ROI, if that money went to pay for medical bills.

I have no idea, but what about investing the money? (yourself into something new, or just into the stock market)
