As you may be aware there is an debate on how to make BTC to have more transactions in block and make network faster.
There is mostly 3 camps - Bitcoin Unlimited, Bitcoin Classic and SegWit.
Bitcoin Unlimited wants BTC to be able to have unlimited sizes of blocks and just yesterday they tried to mine a bigger block than normal network allows.
The block was mined but then whole network was banning nodes broadcasting it for maleactivity. This ended in the block and fees on it to be left unconfirmed totaling of 13.2 BTC loose.
Worth noticing is that it was a bug in the software not actual fork action.
Since the incident alot of nodes stopped using Bitcoin Unlimited and its now at 5,6% of network.
At this point we may assume the only way for Bitcoin to scale right now is SegWit. Im not speaking about whats better or worse software wise - just what has more % of nodes on the network.
STEEM/ BTS vs BTC
Since we are on Steemit lets speak of the currencies here. Transactions Per Second aka TPS is the speed of processing and sending the money.
BTC currently allows 1 MegaByte which is the size of block. This means it can be as many transactions as add up to 1 MB.
So with current model BTC network tops with around 7 transactions.
VISA is 2000.
STEEM/BTS is at 1-2000 right now, last stresstest of 
went to 3 000.
BTS/STEEM allows up 100k in laboratory conditions watch 
So STEEM and BTS are superior to other known payment ways.
Worth noticing that BTS has way cheaper trnsactions than BTC so cost-efficent its also better.
