Yes! You can increase your investment; however, this will create a new investment. Because of this, you can only later cancel or amend this part of the investment.
For example, you had a $2,000 investment finalized, and you later invested an additional $1000. You can now:
- increase your total investment to $3,500 ($2,000 finalized + $1000 new + $500),
- decrease your total investment to $2,500 ($2,000 finalized + $1000 new - $500 decrease),
- cancel your $1,000 investment (before the cancelation deadline) and be left with the original $2,000 investment.
- but you could not reduce your total investment below $2,000.
