My bitcoin value became 10 times

Nowadays, Virtual currencies values are getting high dramatically. Although Bitcoin's value has also been risen, other currencies are risen.
Especially, Ripple(XPR) value has became about 40 - 50 times in this year.

I googled blogs about this matter, some investor got more than 40 million dollars by XPR's value increase.
I am envy of them.

My bitcoin value became about 10 times.
I bought the coin in Feb. 2015.

From a conclusion, My bitcoin became 10 times, but I did not become a rich man.

Because I have only a few bitcoin.

Why did I buy bitcoin?

In 2015, a Bitcoin value is about 2 or 3 dollars.
It is right after news about virtual currency theft. I was interested in Bitcoin and read a book by Yukio Noguchi.

This book recommends that using bitcoin as a money transfer method, not investment.
I do not transfer, I wanted to use purse.io which is a service for purchasing items from Amazon at discount price.

What is purse.io"

Buy merchandise from Amazon at discount price

The system of able to buy discounted price is as follows.

1. Deposite bitcoin into your purse.io wallet.
2. Reveal your wishlist and set discount rate.
3. Wait for someone buy the merchandise in the list.
4. Your bitcoin is transferred to the buyer from your purse.io wallet.

For instance, discount rate 0% means that good's price = amount of payment by bitcoin. Increasing discount rate affect how much you have to pay by bitcoin, it does not affect the buyer.
Why do the buyers want to buy the merchandise on behalf of them? There is a demand that some people want to change Amazon gift into the cash.

purse.io disadvantages

Everyone want to buy merchandise at cheaper price. Of course, there are some cons.

Buyer not always apeear

Increasing discount rate = you can get merchandise at cheaper price. It also means that a buyer less likely to appear.
So, if you set high discount rate, you may not get the merchandise forever.

Limitation of merchandise

This is a major reason. You can get merchandise via purse.io only things. ( I am not sure about current status)
We cannot get Kindle books, also market place merchandise.

Final

I felt uncomfortable on purse.io. I exchanged bitcoin to Japanese Yen. Rest of the bitcoin is in my wallet and I forgot about it.

My bitcoin value is about 6 dollars.
I won about 5 dollars.
