Thank you for your questions, I think the answers to them will be of interest to many.
So, your Q: "how can I make money with this project now?"
A: you can buy sierra on the exchange, set up a masternode and make a profit. Also, you can not install a masternode, but just make a profit by supporting the network, participating in block checks using the POS algorithm. In the future, when you activate the SPOW algorithm and connect your solar panels, you will be able to earn extra money by receiving additional rewards. Also, soon there will be an opportunity to buy and sell solar panels in our PV market - the payment method will be Sierra.
Q: "Why do need a swap? the network is stable"
A: That is not right. We have some code issues in Sierra 2.0 network, and also we want to make all new changes by changing the algorithm and the entire code base - the new Sierra 3.0 network will be based on the Dash 0.14 DIP3 masternodes code base, using all its advantages, such as instant transactions and confirmation for 1 block, improved privacy, stability and functionality
