Step 1. Buy a lot/base. As long as you can reinsure the lot, this will work.

Step 2. Buy 1 to 32 Explosive Crates.

Step 3. Buy 1 Glass Block.

Step 4. Place the Explosive Crates you've just bought onto the lot/base you've purchased.

Step 5. Place the Glass Block somewhere on the lot so that it is easy to shoot.

Step 6. Reinsure lot/base.

Step 7. Buy a bunch of Wooden Blocks.

Step 8. Place up to 32 Wooden Blocks on your lot.
Then remove that same amount of Explosive Blocks.

Step 9. Shoot the Glass Block and then repair the lot.

Step 10. You've just converted cheap Wooden Blocks to expensive Explosive Crates.

Bonus Tip: You've basically just created a block converter. So any blocks you find when looting say a Bandit Base, you can use this method to convert those blocks to Explosive Crates. Which will net you more money/C when sold.

Bonus Tip 2: The amount of charges your Block Recovery tool can have is 32. Hence why I recommend a maximum of 32 Explosive Blocks.

Bonus Tip 3: For maximum laziness, buy Wooden Blocks via C. Then sell the Explosive Blocks for C. This way you don't even need to leave the lot to repeat this process.
Wooden Blocks are also one of the cheapest blocks in the game. So use them for maximum profits.

For Bonus Tip 3, switch out the Wooden Blocks for Grass Blocks instead. They're cheaper compared to Wooden Blocks.
