it has the following advantages compared to BTC an
Let's look at each point and see if they are really advantages.
1. Safer mining algorithm
With a quick look at the code the mining algorithm appears to be pretty much copied from bitcoin. The proof of work algorithm is identical, the difficulty adjustment is identical, and the only thing changed is replacing SHA256d with Keccak
This does not make it "safer".
2. Halving each year
This is not an advantage. This is just a change.
3. Txs burning mechanism / lower supply in the long term
There is no advantage in burning the supply (10% of the fees) apart from trying to create an illusion that "the price should go up just because they are burning coins".
4. Low cost transfer fees (maybe the table could state the actual/approximate transfer fees in $ at the time of publication)
First of all the fee mechanism and the minimums are copied from bitcoin so it is identical not lower.
Secondly when an altcoin is worth less in $$ it is obvious that its fee in $$ is also lower, that doesn't mean the transaction fees are actually lower in terms of the coins you spend on fees.
Finally Fee is not something that can be decided by the protocol, it is something that the market decides.
5. Low cost mining operations (maybe the table could state the actual/approximate mining fees in $ at the time of publication)
9. Hash rate (details)
This is not an advantage that is provided by the protocol or any change they made in the protocol, the only reason why it costs less to mine this altcoin is its lower popularity hence lower hashrate hence its lower difficulty.
Otherwise computational cost of finding a SHA3-256 hash is very close to SHA256 and with equal difficulty this altcoin should have nearly the same cost as bitcoin.
6. Much lower market cap (difference is hundreds of thousands)
This is also not an advantage, you are just saying that the price and supply of this altcoin is lower than bitcoin!
7. BGL NFTs
I personally don't consider NFTs or any tokens for that matter an advantage because so far there has not been any actual use case for tokens in real world apart from fund raising and scamming people.
8. BGL - WBGL bridge on both eth and bsc
I can't comment on this since I don't get it and it looks to be only an idea
#31 not yet available.
10. More compressed size of the blockchain"
I wish it explained "how" because with a quick look at the
primitives I couldn't see any change in transaction and block structure that would decrease the size of the blockchain!
Everything is identical (block header, txin, txout, hashes are 256 bit, scripts are serialized the same way, there is still sequence/locktime/etc, outputs use the same 64-bit amount,...)
Although based on previous points it may mean that "nobody is using this altcoin so the blocks are empty, hence the blockchain is smaller"!!! That's not an advantage provided by the protocol, that's not even an advantage saying the coin is not used by anyone.
Conclusion:
I stand on what I initially said, the changes are minimal and pointless. There is no innovation in this altcoin.
