I assume you are asking what the differences are between Stakecube and Northern?

I hadn't heard of Stakecube before but a quick look at the website shows it is a proof-of-stake pool so people who own a few of one of their supported coins can pool them with others who also hold a few to increase their staking weight. This will give a more regular payout of new coins instead of more infrequent payouts if everyone staked what they owned in a local wallet. In the long term the amount you earn from staking any specific amount of coins will be the same whether they are held locally or pooled. There are a number of staking pool operators and the concept, whilst valid, isn't new at all.

The Northern Equinox Fund is completely different to this.

The Equinox Fund will own and host a number of different masternodes of other coins which have been chosen for their stability and real world applications to give a reliable and regular income. These won't be the 10,000%+ ROI coins that are announced everyday with a MN presale and no coherent application or use case!

The NORT coin will be the native currency of the Equinox Fund meaning that you need to own NORT and use them to buy in to the fund. This means that by buying just NORT you can get exposure to the returns from all of the other coins held in the Equinox Fund which spreads your risk, simplifies investment in crypto and allows people who don't have (for example) $200,000 to invest in a DASH masternode to get a piece of the returns from one.

It's a relatively simple concept but one that will make crypto investment simpler and more attractive to both old and new crypto enthusiasts!

The current whitepaper is here (https://cdn.discordapp.com/attachments/416697792048922636/461555510496329728/Northern-Whitepaper-v1.0.0.pdf) with more details and an updated one is due to be released in the next couple of days.

Hope that answered your question and thanks for the interest
