Explaining to others why my digital portfolio is 80% EOS is always a simple conversation for me. The 'price' of EOS is not a significant factor, to be honest, so when the price drops I see a sale on and an opportunity to strengthen my position
Owning traditional real estate has always been a principal moneymaker since currency emerged, ask the English royal family, they are doing ok for sure. Owning real estate means control over your financial future.
Well, holding EOS tokens means that you are reserving potential "compute" resources such as network bandwidth, storage and soon to be IPFS access. You gain access to these resources by staking your tokens via an EOS smart contract.
So EOS tokens are actually a digital commodity needed to run dApps on the network and by owning tokens, you have some control over when you can use these resources. This means that when (not if) the price rises, there will be a market for token leasing that you can monetize and start to pull in a passive incoming with minimal effort on your part.
Chintai is a dApp that will allow you to rent these resources to others who need them. They will have a web front end similar to the traditional cryptocurrency trading platforms with matching engines to automate the process.
This really is the digital equivalent of renting a house, these tokens will always belong to you (unless you sell them) and you will maintain ownership of them whilst making a passive income.
There is also a lot of talk around a RAM trading market as RAM will be the most valuable resource on the network. As RAM depletes on the current chain, the price of using it will rise. If RAM gets to a 'critical' level, a side chain will be spun up and new RAM allocated. This means the price of RAM will drop as a new fresh batch will be available, so this market will need more of your time if you want to make a profit from it.
Dan has already commented on this and recommended that the launch team do not make the entire RAM allocation available at launch to stop people from buying up too much and making the network unusable (humans always allow greed to get in the way of a good thing). I believe the launch team have taken his advice on board and are working on agreeing on a RAM allocation value.
In summary, there are multi ways I can earn a second, third and maybe even a fourth income just by owning one token (don't get me started on the airdrops).
