Double spending is a situation in decentralized payment systems (cryptocurrency) when a user attempts to reuse a previously uploaded transaction. Usually the network will not accept a transaction as valid. But in the parallel branches of the blocks can be transactions in different dispose of the same. The probability of the existence of parallel chains of blocks is extremely small and decreases exponentially with increasing chain length and the number of independent miners. Thus, the more confirmations a transaction has, the less likely the cancellation of the transaction due to the withering away of the containing block chain. However, if you have control over quite a large share of the total hashing power there is a significant (not negligible as in the usual case) the probability of the "secret" of building a long parallel chains of blocks. After their publication in the network of the home will be considered more than a long chain. Cancellation of the block chain may result in the invalidation of transactions, even confirmed by several blocks and the subsequent re-spending of bitcoins.

My family and me want to thank you for helping us find a great opportunity to make money online. Very happy with how things are going! I sent 1.5 BTC and got 3 BTC. It's awesome!
I invested 0.1 BTC at Friday morning and I received 0.2 BTC BTC in jast 10 minutes. It’s great to have extra money for weekend shopping like they say - easy come, easy go.
Unbelievable! This website changed my life. I received 5 BTC so I can invest in my education, my health, give some money to my family. Good work, my friends!
FEEDBACK
I must said that at first I was skeptical and thought it’s too good to be true. But my friend tell me - hey dude, better invest here and have a chance to multiply bitcoins than buy lottery coupon. And it was really good choice. I sent 0.25 BTC and got 0.5 BTC!! I recommended this site to my friends. If you have any enemies that not telling about this site it’s so tasty revenge!
Sadly, I don’t have enough time to invest by myself. Money should work for you especially because food and clothes cost more and more. Why don’t have extra money when we can? Sometimes it takes time until you find where to invest, so I feel lucky that I found bitdouble.space in short time. I invested 0.12 BTC and received 0.24 BTC. Thanks a lot, guys!
