I think you referred bitcore instead bitcoin core? Bitcoin Core based on Wiki https://en.wikipedia.org/wiki/Bitcoin_Core . If currency, then it is bitcore, not bitcoin core, because i never heard currency called bitcoin core.
If you want buy bitcoin, don't buy on bitcoin.com. Try other option such as localbitcoins.com or other exchange that already mentioned above.

Oh iya, kalo ga salah ada yang namanya wallet Kasse. Kemarin aku jumpa post di bitcoin discussion yang bahas tentang Nano S dan Kasse(serius belum pernah denger namanya). Mungkin bisa di masukkan ke dalam list, karena menurut review di website2 cukup bagus.

Semua wallet beresiko kalo ga ada backup, entah itu dekstop wallet, mobile wallet maupun hardware wallet. Apapun walletnya kalo ga ada backup ya resiko, kan sebelum mengoprasikan wallet apapun (yang ada backup kayak private key atau seeds) pasti di awalnya disuruh ngesimpen backupnya dulu baru digunakan.

I bet the hacker already know how the bitcoin work, and he will wait the transaction confirmed first before he send you a decryptor.
If you don't want send money to that hacker, then just don't send it. After bitcoin transaction get confirmed, then you can't reverse it or cancel it.

Don't pay anything to that hacker, i read a story on another forum if the hacker doesn't give your files back or key to decrypt it after he paid him.
Did you already check the ransom decryptor? Some antivirus company create it for free, such as McAfee, AVG, Kaspersky and Bitdefender. Just take a look at the last extension on your files (ex : ransom.jpg.ransom) and try to find the decryptor. However, not all ransom have decryptor, you maybe can contact some antivirus company to create the decryptor (probably will not free).

Actually, there's a community that offer free if you have the ransom note and encrypted file, just send it to them. MalwareHunterTeam, but idk if they can help you or not.

That's old site, is not bitcoin mining, that just another ponzi/hyip scheme. Because you will get paid if someone do deposit on there.
Some cloud mining like genesis, hashflare and hashnest claim if they're not ponzi, but still hashflare and genesis looks like have problem with their profit, since the maintenance fee is too high. But, still i don't know if they're 'legit real' cloud mining or not.

Move this to Scam Accusation, because this doesn't belong on here. It will be good if you using Scam Report Format (Use it to make scam reports properly).
Anyway, thanks for informing us, hope you can learn lesson from this. I'm sorry to hear that.

Coba cek di post https://bitcointalk.org/index.php?topic=4955383.msg44804091#msg44804091 , ada beberapa informasi tentang mining.
Menurut yang ku dapat, rtx kurang cocok buat mining. Orang-orang pada bilang hashratenya tidak sesuai ekspetasi dengan harganya yang cukup mahal. Tapi ya, kurang tau , karena itu menurut kata orang-orang dan aku sendiri juga belum test langsung.

Hmm,, let see...

Menurutku, jangan terlalu takut ngeluarin opini terhadap member lain aja sih, dulu sebelum aku banyak merit jujur aku sendiri mau post atau komen gini takut, komen gitu takut, takut untuk di salahkan dan sebagainya dan aku yakin ada beberapa para member yang ingin mengutarakan opininya tapi takut entar di kritik oleh rank member lebih tinggi. Karena kuliat di forum ini, rank member rendah kurang berani mengutarakan opininya. Tapi kalo ngeluarin pendapat juga harus masuk akal dan ga menyimpang jauh.

Jangan pernah komplain dengan merit, atau cara dapetin merit susah. Kemungkinan kalian bisa terkena "Ignore" sama beberapa member, terutama orang luar, karena jika post tersebut tidak mereka suka atau terlalu sering ditanyakan, biasanya akan di ignore dan kesempatan kalian dapetin merit juga berkurang.

Pelajari bahasa inggris sebisa mungkin, bahasa inggris kalian tidak perlu "Perfect", hanya gunakan saja grammar dan kosakata yang sesuai. Asalkan pembaca mengerti, maka itu tidak masalah. Mendapatkan merit di sub forum lokal atau indo itu sama saja, ga jauh berbeda. Jadi usahakan bisa menggunakan bahasa inggris yang baik dan benar.

Personal Tips : sering-sering lah kunjung di sub-section "Meta", "Reputation" dan liat bagaimana orang disana berdiskusi dan sesekali mainlah ke section "Serious Discussion"

Karena sisanya udah di sebutkan oleh member-member di atas, maka saya ga perlu menuliskannya lagi. Jujur saja saya juga rada bingung mau ngasih tips gimana, karena saya sendiri juga ga terlalu mengharapkan merit, jadi pingin komen dari malem bingung, lol. Tapi, semoga memberi motivasi.

Fun Fact : Taukah kalian, kalau orang yang pandai bikin humor dan nge-sarkas juga bisa dapetin merit dengan mudah?? Well, jika kalian membaca ini, coba temukan postingan-postingan yang lucu dan di beri merit di forum luar.

https://imgur.com , di saya bisa di buka tanpa vpn dan semacamnya dengan mudah dan tanpa masalah. Entah kenapa kok rata-rata pada di blokir  

So, can i still using shapeshift without KYC? Or i must do KYC first now?
Sorry i can't open the site, idk why. I hope i can still trade without do KYC first.

The first one looks interesting, since you said they can do exchange with less than $1. Will give a try.

Edit:
Ah, okay. Thanks!

Yes, you can. IIRC, Newegg and Overstock accept bitcoin and they sell something 'real' such as computer parts. furniture and etc.
You can also purchase something from amazon with bitcoin through purse.io like comment above said.

Coba mainnya lebih sering ke forum luar, terutama Meta. Disana ada sticky post, ku quote in yang penting dan ku tebelin

Oke, sepertinya pertanyaan tentang di bolehkan atau tidak udah terjawab dengan font yang ku tebelin, diperbolehkan TAPI tidak disarankan.
Masalah Red Trust tentu saja fatal, contohnya kalo misalkan akun yang dijual sangat bagus dan punya reputasi baik sebagai dealer sehingga orang forum percaya kalo mereka ga perlu pake escrow lagi, terus akun tersebut di beli scammer, dan boom, dia bisa ngescam orang dengan mudah di forum ini dengan menggunakan reputasi sebelumnya. Makanya biasanya terkena/diberi Red Trust.

Alasan lain karena bisa saja beli akun cuman buat ikut signature atau bounty doang, biasanya buat spamming menuhin bounty atau signature campaign mereka dengan low quality post mereka. Maka dari itu mereka di beri red trust agar tidak bisa ikut bounty lagi.

Oh ya, judulnya mending di tambahin "?" (Tanda tanya). Karena judulnya kesannya seperti bertanya.

Ada yang lebih lengkap, silahkan cek di web berikut https://en.wikipedia.org/wiki/History_of_bitcoin , disitu juga dijelaskan alasan mengapa dan sebab bitcoin harganya berubah-ubah. Bisa juga di website berikut https://99bitcoins.com/price-chart-history/ dan masih banyak website yang memberikan informasi dari awal diciptakan hingga sekarang. Bahkan web explorer juga membuat live chart harga bitcoin dari awal https://www.blockchain.com/charts/market-price?timespan=all, walaupun ga ada informasi lengkapnya, berbeda dengan 2 website yang saya sebutkan sebelumnya.

Create thread on Scam Accusation, most of people usually come to that section to see if there's a new scam accusation. Don't forget to follow Scam Report Format (Use it to make scam reports properly).

I will go with Ledger Nano, since its already quite popular and reputable. To be honest, i never heard Kasse before. I did rather chose something that i know. However, people always have different opinion. So, maybe someone that already used kasse will share his opinion here.

At least, people will not fall to that site easily, because their captcha is error


except they still want to try login with error captcha or they didn't notice the captcha.

Have you tried with different ISP? I tried use another ISP and i can't log in, well the problem is different from yours but maybe you can give a try. Also, try use VPN too.
Since its probably problem with your ISP, try restart it or reset(if it can).

Edit :
You can try use VPN that appear on mycelium wallet(click for screenshoot) SaferVPN but for me its too expensive. For free i use Hotspot Shield. But well, i rarely using VPN except for opening app that blocked in my country.

Ya dan sedikit benar, taukah kamu kalo Indonesia adalah salah satu board yang dikenal banyak "Spammer" dan "Account seller" di mata orang luar? Ya karena mereka itu. No offensive ya buat yang mungkin ke triggered, cuman nyampein aja.

Kebanyakan rank tinggi jarang nongol di mari (well, ga semua), coba cek di sub forum inggris, ada beberapa orang indo juga yang cukup bagus dan worth buat di baca.

Btw, kalo misalkan post saya tidak seharusnya ada disini, silahkan di hapus saja.

Did you use any VPN? Did you already uninstal it and install it again? Since i can log in with 1 MB/s connection speed without problem. I try to search on google and found This
Maybe the problem is on ssl, maybe you can try to fix it, try this article.
I can be wrong but hope this fixed your problem.
