“I have one big idea and limited savings. Play it safe or bet on it?”
Neither, until you value it. Write the story first: who pays you, why they pick you, what kills it. Now attach a number to every sentence of that story, revenue you can defend, costs you have checked, a failure rate you can live with. If the value that falls out is several times what you would put in, and losing the stake would not end you, the bet is the rational choice.
If the story only works in spreadsheet nirvana, keep the savings. All valuations are wrong. Make sure yours is wrong in a survivable direction.
