私钥库也不一定是假的 只是要找到对应的公钥的概率几乎等于零
这样说有一天计算机有重大突破的话 比特币体系会崩溃吗?
你说现在的银行密码是6位数字,到现在还没有崩溃是奇迹吗?
因为银行的密码不允许穷举 你试几下它就自动冻结了 而且庞大算力入侵银行系统 银行是会知道的
但是一切皆有可能嘛
是不是持有比特币的人敌视一切不利于比特币言论!
但比特币的确存在很多缺陷,不要无视!如挖矿而消耗很多电能,忘记钱包密码或钱包丢失~币就永远消失了,或者 拥有者突然死亡币就跟他永远走了(除非他事先告知了他人...),还有数量上限固定~通货紧缩,目前看比特币沦为炒作对象~难以成为国际支付的数字货币,只是一种被投机炒作的东东。
你所说的确实是比特币存在的一些问题,但并不代表这些问题是致命的。一些问题在法币身上也存在。

转摘:
作者:lm68001
通过key.btc123.com,可直观了解比特币共有10的77次方个密钥和公钥(地址)对。这些密钥和公钥(地址)对随机产生,破解密钥只能用枚举法。如果用全部矿机算力来破解密钥,我们来算算需要多少时间。
假设:比特币矿机算力全部用于解密,算力为6×10的16方每秒hash;全世界人均2个比特币地址,为10的10次方个;一年为3乘10的7次方秒;密钥对平均分布。
则:解密一个密钥对时间为10^77/6*10^16/10^10/3*10^7=5.5*10^42年,大概相当于宇宙诞生至今3.7*10^32倍的时间。
如果假设20年后,人均2000个地址,算力增长10亿倍,解密一个密钥对时间仍需3.7*10^30次方年,相当于宇宙诞生至今3.7*10^20倍的时间。
注:1、比特币矿机是目前全世界最大最快最专业的哈希函数计算机群,用于解密比特币优于任何超级计算机,其浮点算力已超过世界前100位的超 级计算机合计算力的上百倍。
2、矿机算力是一秒计算hash函数的次数。如果生成一对密钥,并验证有否比特币,需要的时间更长,算力高估。
3、全世界按60亿人计算。
4、从宇宙大爆炸起点至今约150亿年,1.5*10^10年。

我并没有说BTC123,只是他个人的说法会让人不理解。
