I think buying a bitcoin is enough for your children or grandchildren. Cost is less but efficiency.

IMHO, who can predict the future? Maybe bitcoin will gone suddenly.

If you know what I am talking about...

i think bitcoin can't disappear banks.. because most of the people don't know about bitcoin... almost all the people use banks and that won't depends upon educated or uneducated, rich or poor... and most of the people trust only the banks... so after few years bitcoin will be popular but still banks will be there...

Just saying, why use this at a merchant? There's no reason to so just don't. And what if you accidentally use an address you just have away the private key for?

Having said that, I love this for personal use and hopefully version 2 will support private key transfer over a segregated nfc chip.

wow 30 juta..besar banget modal nya gan heheh..btw udah balik modal belum?

bagus gan.semangat ya bikin skripsinya.semakin orang tau.semakin meningkat harga coin nya wkwkwk

bitcoin semakin meroket..karena banyak investor yang berdatangan...dan seiring susahnya untuk mendapatkan bitcoin pada sekarang ini..maknya harganya semakin mahal...dan diprediksi bisa meningkat lagi

iya benar gan memang china bangsat.bikin dumping harga altcoin dan btc aja
