Ripple and Golem are two good ones that i can think of.

Ripple is distributed protocol to move money around the world, but the concept is very good and the tech behind is already proven on a large scale.

Buying ripple can be beneficial as their value would increase with more bank tie-ups and when customers start using them, so it might be a good investment.

Golem Project holds a lot of potential value for the future, as it would effectively create a truly global, open sourced and decentralized Web.

Combining the power of computers all over the world would provide all of the necessary hardware resources, and Ethereum-based payments will clear transactions.

Disclaimer: I have invested in GOLEM and Ripple. This is just my personal opinion on the project. If you like to invest, Golem and Ripple are available on

The biggest problem with bitcoin is not the adoption, financial or economics part of it. I like the idea of blockchain technology but the power consumption of the mining process is making it unsustainable. Unless all the mining operations moves to sustainable renewable energy, the power consumption of the network is going to exceed the total energy consumption of a mid-size country.

How does bitcoin work? Who actually pays for the mining done?

As you may already know, Bitcoins are blockchains which work on distributed network. Now, just suppose that I am a hacker and I want to perform a ‘man-in-the-middle’ attack while sender A is transferring BTC to receiver B.

Can I do it? Yes.

But will it be valid? No.
Why? - Because BTCs also include something called as ‘Hash’. If I try to change any part of the BTC in the middle, the hash value will chain and when this chain will be validated against all the distributed network across the ledgers, it will simply pop-up as irregular and henceforth discarded. What it means is that a single computer will be fighting against all the computers on the network if they want to make the transaction valid and transfer the BTC to attacker’s account.[1]

BTCs go through the complete check every single time a new transaction is made and verifies the validity of the block against other nodes.

Yes, I believe you should invest in Bitcoin.  But when I say invest, I don't just mean obtaining some bitcoins and holding on to them, only to sell them at a profit later.  I mean investing by spending time and energy learning, discussing, using, coding, and enquiring about Bitcoin.  The arrival of Bitcoin as a new financial technology heralds a time for us all to consider deeply what gives anything value, and why we do (or don't) use a form of money for a given exchange of goods/services in various circumstances, and why we have money in the first place.

Bitcoin will only take on value because it meets a need within society that existing commodities don't meet in the same way.  I hope that people will learn more about what makes Bitcoin different from other forms of value and why it works well as a form of currency, and then use it, spend it, accept it for goods and services that they offer.  Simply investing in something, keeping it stored up doesn't do all of us much good.  Getting Bitcoin to a point where you and many, many others utilize it as a part of an economy because it is more efficient, affordable and convenient to use will benefit us all. 

If, after researching Bitcoin, you do decide that Bitcoin would be a good thing for society to embrace (and I do), then I'd encourage you to invest time promoting, discussing, using, protecting the use of Bitcoin and building systems to allow for Bitcoin to be utilized by as many people as possible. And if you happen to make a profit on *SOME* of your bitcoins along the way, then more power to you.
