Most young and little-known marketplaces have the same problem: sudden disappearance. They are closed, and users who kept money on the exchange, remain, as in a fairy tale, at the broken trough. But only in this case the situation does not end well: it is impossible to return the money. Perhaps that is why traders choose popular exchanges for fear of losing their virtual savings.
TOPBTC is at risk for all safety and reliability indicators. And if the administration of the site does not even think to disappear with the money of its traders, the hackers are not asleep. They closely monitor such exchanges and are ready to steal users ' money at any time. Because the resource TOPBTC has no special protection.
There is no protection against DDOs attacks. There are no restrictions on entering by ip-address. About other modern methods of protection generally silent. One two-factor authentication and the installation of a pincode for a financial transaction is too small to ensure the full reliability and safety of money in users ' accounts.
