I didn't yet spend $1 on cryptocurrency and also the return on it. I'm just earning bitcoin in this forum and I'm expecting that I would get the biggest amount of it. Bitcoin is the highest in all cryptocurrency and all people know that bitcoin price constantly fluctuates so, there's a possibility to earn and have a high profit from it. I was joining in signature campaign and then they payed me depends on my rank. Saving my bitcoin in my wallet has a big chance to return with a high profit.
