Then you spend them too much. Try to only spend bloonstones on upgrades (don't be tempted by the continues!!!) and stockpile them. Don't buy every tier 4 upgrade possible - just those you need. The only ones you will likely want are Ring of Fire, Blade Maelstrom, Bloonjitsu, Bloon Impact and Spike Storm. If you play deep-round CT, add Sabotage Supply Lines, Temple of the Monkey God, MIB Call to Arms, Banana Research Facility, Artillery Battery and Overclock. The rest are pretty much pointless.

For continues, just don't. If you failed the first time, who says you'll pass the round with another $1000 in the bank? And once you lose again, you will probably use more continues. Don't start or you won't stop (speaking from VERY bad experiences).

If you play Flash, just NLL tiles for bloonstones. Special missions and volcanoes can give a hefty bonus. As for mobile, just send MvM attacks whenever possible (ideally 15+ times per day). Can give up to 100 bloonstones PER DAY!!!
