I used to play survival a year ago, then I took a break for a year. I decided to reset myself and start fresh, since land claims broke a year ago, and people had already griefed my old base. 

Voting is one of the best ways to make money, and I made around 30k and got some pretty good gear out of it. I even was able to gamble out a champion key. The stuff you get out of it is usually better than the 1k you get by voting on a single site.

Another great option is bartering with salespeople, and selling the thing that you bartered for, for more than you paid for. One thing that I got a lot of money off of was mending. One dude was selling it for 500 per book, so I took it as a great opportunitty to sell them for 2.5k each, effectively quintupling the money I spent on them. 

Another quick and easy way is jobs. When you're mining to get some good ores to sell, or digging sand to smelt into glass, and sell, or any other money method involving getting resources, jobs can help you make a little extra cash to sweeten the time that you're spending mining resources. 

For the final stretch of my 100k, I found an elytra for 50k on the auction house, and I fully enchanted it. Buying the enchants costed around 2k, but it was worth it, as I was able to put the elytra up for 65k, making me 13k profit, and making me get up to the 106k that I just got today.

I did spend like 50k to get some parts of my gset, the other ones I made myself.

necroing to keep this post relevant

Lol, good job, but when you are more Progressed, it can take only minutes to earn 100k. For a starter, I have some ways to make 80k per hr using the shop only.
