Getting Started with Cryptocurrencies – Common Questions


You have just heard about Bitcoin (BTC) and how if you have held $100 worth of BTC in 2011, you would have > $70 million now. You may be thinking of a few things:

  • If only I bought that $100 worth of Bitcoins, I would be lying on the beach of Maldives, sipping on my glass of martini.
  • Now the price is so high, it’s probably the worst time to buy any.
  • Also, my friends were telling me it’s a passing fad and the bubble may burst anytime.
  • By then, I’ll probably be lying under the bridge, drinking rainwater collected in my inverted umbrella.

Let me ease you into getting your hands wet and join the crowd by sharing my two cents on the above points.

Trade Bitcoins in Singapore

Buy/Sell Bitcoins in Singapore

Buy Bitcoins

Sell Bitcoins

Buying and selling bitcoins in Singapore can be very perplexing for first-time buyers.

As an early adopter of technologies, I’ve been there myself. I’ve got my first bitcoins on Localbitcoins back in 2014. Since then, I’ve dealt with various platforms like Remitano, CoinHako, etc.

However, I’ve realised that most people do not want a deep dive into bitcoins on day one. They just want to get their hands onto a bitcoin or two without the hassle of understanding how bitcoin works!

While I trade bitcoins on major marketplace, where they provide a safer environment for everyone, I’ve offered my buyers/sellers options of conducting the trades off such platforms to receive better pricing.

So I’ve thought of extending this service to you if you would like to buy/sell bitcoins in Singapore.

Finding Dratini Nest w DBSCAN


My previous post documented the method I’ve used to rank the various Pokemon Nests. For many beginners, the whole process seemed to be a little lengthy. In this post, I’ll be showing a much faster way to search for the nests amidst the noise using another clustering algorithm, DBSCAN. I’ll be using the Dratini Dataset for this process.

And now… Here’s the information about the upcoming data mining talk!

Data Mining Pokemon Nest (Part 3)

First of all, thank you for your support for the previous posts. If you’ve missed the post about ultra-rare Pokemon, it’s here. If you’ve missed the one on the starter Pokemon, it’s here . This post will cover the remaining Pokemon nests in Singapore, featuring Dratini’s nest for players to farm up their Dragonite.

With this post, most of the Pokemon nest will have been revealed with the exception of Gastly, Hitmonlee, Hitmonchan & Likitung.

Staring at the Grim Reaper in the Eyes


So many time I’ve told my girlfriend that a particular startup is dead (or in most of the aspects, have no future). There is so many ways a startup could die. From having no money, to having too much money. From having too many specialist to too many generalist. During one of the coffee breaks I had with my interns I told him Captivoo is dead. We were on the topic of the future of the company…

First Week of ‘Internship’


So it has been a week of working full time on Captivoo, my startup. I never knew that so much could happen in a week, and the experience to be so different from what I’ve imagined. I’ve decided to capture random snippets of thoughts and work schedule on my this blog to hold myself accountable to the growth of Captivoo. There will be at least one blog post every week as I reflect on my past week and plan for the next.

If you are reading this, feel free to laugh and learn from the mistakes I will be making along the way as a founder.
