Coins: A trustless sidechain protocol

Hi all,

I've been working on a sidechain protocol with no trusted third party. You can find the whitepaper here.

Abstract. Coins is a Bitcoin extension designed for payments at scale. We propose an efficient solution to the double-spending problem using a bitcoin-backed proof-of-stake. Validators vote on sidechain blocks with one-time signatures, forming a record that cannot be changed without destroying their collateral. Every user can become a validator by locking bitcoins. One-time signatures guarantee that validators loose their stake for publishing conflicting histories. Checkpoints can be additionally secured with a bitcoin-backed proof-of-burn. Assuming a rational majority of validators, the sidechain provides safety and liveness. The sidechain’s footprint within bitcoin’s blockchain is minimal. Spawning multiple, independent instances scales horizontally.

Feedback is highly appreciated!

Thank you

PS: Here on Github you can find further research on scalability and usability

A theoretical look at the last 1000 days of DCA (dollar cost averaging)

I ran a simulation of performing DCA based on a start date going back 50, 100, 150... 1000 days. Here are the results. The simulation assumes a 0.50% taker fee on each buy and investing $1 a day. You can simply multiply all by 20 to do $20 a day. The min column assumes you bought at the worst time each day (24h high), and the max column assumes you bought at the best time each day (24h low). The APR is what standard APR would be required to yield the same returns over the same period. The brackets show that your final value is below the amount invested.

For example, if you would have started your DCA at the ATH (756 days ago) your would still have realized an 8-10% (apr) gain. If you would have started at the 52w high (200 days ago), you would obviously still be underwater, but not by as much as most would expect.

It's an interesting example of how DCA can "iron out" some of the volatility.

Assuming a current BTC spot price of 8070.00 and that you started your DCA so many days ago

Number of entry days in the last 1000 that would result in a loss: 167

A better, more user friendly simulator can be found at dcabtc.com ⁽ ^not ^my ^site ⁾ , I just provided a table for those wanting a quick high level view.

So if your terribly concerned about when to enter the market, just try a dollar a day, or $10 a week.
