If you are a regular trader you may use this offer:
My friend is a 24/7 crypto-trader. He makes a living from it. As a regural client at
https://btcto.money he received a Promo code which gives better exchange rate when used.
Everyone can use this code, however there are some rules to follow. Here is my friend's quote
"The code can be used only once per customer. So if you have access to couple different paypal accounts (family,friends) you can use it more than once, otherwise you can use it just once"
So if you have access to more paypal account, you can probably make some good money on this...
The promo code is: xZy15wKq
Basically you can buy bitcoins (for $450 each) at
https://www.coinbase.com and sell at
https://btcto.money with the promo code
xZy15wKq (for $515 each). But you can do it only once (the offer is limited to 1 use per paypal account).
If you have enough Bitcoins you can make some good profit.
For example buying 20 Bitcoins at $450 and selling them at $515 will bring around $1300 profit.
