I believe the best way to reach an evaluation of bitcoin 2 is to compare it to the OG bitcoin since bitcoin 2 claims to be the best bitcoin alternative.
Both cryptocurrencies have the same maximum supply of 21 million. On 5 February 2018 bitcoin 2 forked from bitcoin meaning each individual owner of bitcoin also got some btc2. The supply of the two cryptocurrencies was also the same at the time of the fork on block number 507850.
Bitcoin2 uses a proof of stake algorithm over bitcoins proof of work. I personally think that proof of stake is more efficient than a proof of work algorithm but you can do your own research on that. Like every other fork of bitcoin, this one also has a shorter block time at one minute. Logically you can also follow that it can allow more transactions in a day.
They do have a privacy protocol called zBTC2 but as of writing it is disabled and they are working on it. I will update this as soon as it is finished.
Let's not forget that this is a proof of stake coin so there are potential gains to be had. They claim that running a masternode rewards you 55.53% as long you are holding 1000btc2 and you can follow the guide here. They claim if you stake any amount of coins it will earn a 21.92% return.
Now before you go out and buy btc2 I want you to know exactly as I was writing this a pump and dump article came up against btc2. I'm not going to tell you what to buy and what not to buy. I will simply advise you to DYOR and if you do decide to buy maybe I will regret not buying.
