How to Double the Amount of IOST with Constant

This tutorial is conducted by a Constant team member.

At first, I had 100,000 IOST in my wallet.

I used them all to borrow USD.

With 1 IOST = $0.004979 USD (as of January 6, 2020)

After getting matched, I received $329.82 USD in my Constant account.

I used this money to buy IOST on Binance, I got 66,242 IOST coins (1 IOST = $0.004979 USD)

Next, I continued to borrow against the IOST I just bought (66,242 IOST):

After getting matched, I received $218.48 USD

I continued using this money to get 43,880 IOST coins.

Again, I continued to borrow against 43,880 IOST coins:

After getting matched, I got $144.72 USD, then I used it to buy another 29,066 IOST coins.

As you can see, starting from 100,000 IOST to: 100,000 + 66,242 + 43,880 + 29,066 = 239,188. I now have over x2 amount to hold. Imagine the price going up, I will make more money than I normally should have.

But remember, If your IOST collateral goes down in value, specifically down to 125%, 120%, and 115%, you will need to top up more coins to keep the original value of your collateral will be liquidated. If your IOST collateral goes up in value, you can recall the excess. You can manage your loans through your Constant Account page so you know how much to repay and when.

Happy Borrowing!
