Saya rasa akun apapun bisa dihack, namun seorang hacker tidak asal melakukan hack.
Seorang hacker adalah manusia biasa yang tak terlepas dari sifat emosi (terbatasnya suatu kesabaran), biasa nya mereka melakukan ini jika ada yang membuat dirinya kecewa atau kesal, sehingga timbulah niat/tekad kejahatannya untuk melakukan hack (tindakan balas dendam).

Cryptocurrency to invest for 2018 is :
Bitcoin, Ethereum, Bitcoincash, Ripple and Bitcoin Gold.
keep holding them till the market stabilizes and you get returns. All coins which suggested in the list are good coins.

Jika itu terjadi di Indonesia, justru saya merasa sangat khawatir, sudah pasti sirkulasi keuangan di Bank-Bank akan merosot tajam, imbasnya adalah Beberapa Bank Micro mungkin akan tutup.
Mungkin dalam 1 atau 2 bulan selanjutnya Ratusan bahkan Ribuan Bank yang ada di Indonesia akan diLIKUIDASI oleh Bank BI, semua itu dikarenakan tidak adanya masukan/pajak (penghasilan Bank dari berbagai jenis Transaksi) dari para nasabah, akhirnya mereka tidak bisa beroperasional dengan baik yang akhirnya mereka akan tutup (bisa juga ditutup).

In i am view, Market demand for Cardano, MonaCoin, Nxt, Bytom, FedoraCoin, Cofound.it, Genesis Vision, MCAP has proven strong and the next x10, x20, or x30.

For me bitcoins are scarce, useful and invaluable. So, I use it for everyday life expenses and reinvest.
Investing in Bitcoin is one of the most best for me and I made it as the first source of my income.

By burning those bitcoins did not in any way diminish the amount of bitcoin present in bitcoin network.
In the technique, bitcoins are (burned) by sending them it to an address that is guaranteed to have no known or discoverable private key. Means, that those coins can never be used again.

Bitcoin and Altcoin is a form of digital currency, is two different types of cryptocurrency, and transactions are made with no middle men (meaning, no banks).
Bitcoin and Altcoin have helped millions across the world, to reach their destinations faster and more safer (in transacting).

Yes, there are obvious differences that are visible to all, Among others:
Bitcoin is one Koin that has been a types of cryptocurrency in the market for a long time until now. And altcoin is any digital cryptocurrency similar to Bitcoin “alternative to Bitcoin” and is used describe any cryptocurrency that is not a Bitcoin.

Bitcoin was created by an unknown person or group of people under the name Satoshi Nakamoto. While altcoins are created by diverging from Bitcoin consensus rules (the fundamental rules of the cryptocurrency’s network) or by developing a new cryptocurrency from scratch.

Bitcoins can be attempts to enrich anyoneanyone (investors and traders).
While some altcoins can be attempts to enrich founders and offer little new.

There are tons of traders in the market who take different approaches to trading. Some sell, others only invest. Some traders will utilize the market for bring in some extra income.
I think, Buy and Sell are both good.
In any condition, with one condition "Use the correct position".

Sekalipun jaman berubah, Bitcoin tetaplah mata uang virtual yang unik dan paling bisa diterima oleh orang-orang dibelahan dunia/seluruh negara.

Nah ini baru benar saya setuju dengan anda, soalnya saya pernah mengalami itu bahkan sampai Rp 325juta dan tidak ada potongan biaya sama sekali untuk transaksi ini, dulu lampiran yang saya bawa cuma KTP Asli/KK Asli/SKU (Surat Keterangan Usaha) dari desa.

ETH seems so much better today and can be profitable,
I thought this is a good time, OK! I`m don’t want to waste my money and I will invest there.
Because I felt confident i were going to get a profit.

Pada saat itu sekalipun (bitcoin habis di mining) rantai blok otomatis terhenti, namun bitcoin masih bisa hidup, cara menghidupkannya yaitu dengan cara menggunakan bitcoin sebagai metode pembayaran dalam tiap pembelian barang apapun. Dan ingat!, pada saat itu harga bitcoin akan mencakar langit, hal ini terjadi karena langkanya pasokan.

This only confirmed the difficulty in price prediction of Bitcoin.
If you are interested in Bitcoin as an investment
Buy bitcoins, and keep them for a relatively long time. Resist the temptation to sell more, unless you thought about it very carefully.

Jika modal anda benar-benar sedikit, cobalah dengan salah satu Altcoin terbaik yaitu ethereum, karena saat ini ethereum sangat berpotensi jika dibandingkan dengan altcoin lainnya, sepertinya dalam beberapa bulan terakhir ini ethereum akan mengulangi memory "Bulan Diranting Cemara" seperti yang pernah terjadi dibulan lalu.

What you say Is true, ethereum on the top biggest of altcoins today.
Others can argue that something such as Litecoin has a better chance of filling a need than Ethereum. Yet my feeling that says, ethereum is the best altcoin.

The features that a good investor should have:
Professional, Have a broad insight, Positif thinking, Honest, and Patient.

The characteristics of people who have enough capital and earn money from money.
Have a strategy, Full-time career, Approach trading in the correct way and Loving what it does.

What are the factors that make these people successful in their investments.
Usually, they focus on (Preparation, Experience, training, consistency, profitability, and persistence),
They have enough money to cover expenses for an extended period of time,
And also they approach this as their new career and job at all times of every day.

Samalah bro, aku juga enggak yakin tuh.
Tapi meskipun begitu saya masih tetap berharap "semoga Departemen Kebijakan dan Pengawasan Sistem Pembayaran Bank Indonesia" dapat memberikan regulasi yang jelas terhadap Bitcoin, agar saya selaku pengguna Bitcoin tidak merasa khawatir.

Here’s what we now know about the Ethereum.
Since the first, Ethereum it`s movement looks promising.
For example, on this Thursday (November, 23/2017), the ethereum price hit the a more than $ 399.03 ~ $ 400.46. I think, Etereum has way more advantage than Gold.

I suggest, "Don’t chase bitcoin prices." Decide on a entry access and stick with it. With bitcoin, you’re almost always right in terms of foreseeable price action. Be patient, and let the Bitcoin price come to you.
When bitcoin has reached the right price, i`m suggested that investors refrain from buying their bitcoin all at once, they should invest a little at a time, wait for a bit, and then invest some more.
