Steem and Bitcoin are, apparently, different cryptocurrencies.
Bitcoin is the pioneer among cryptos. Steem is considered an altcoin.
Bitcoin is the number 1 cryptocurrency. Steem is at the level of 40s.
Bitcoin's value is at $3,500-4,200 recently. Steem is at $0.3-0.40
Bitcoin has no social media dapps. Steem's product is Steemit, a social media dapp.
steem is faster, has 0 fees on transactions on the block chain, and cost less
bitcoin is the original currency, it is very slow. transactions can take over half an hour. transaction costs can be high, bitcoin is also much more expensive and most other coins follow its grapsh for highs and lows on the market.
Steem has a social platform and dapps btc is the father of all crypto and is considered as a store of value. Steem has another consensus algorithm Delegated proof of stake. User can decide who to give money to. It's free too. No transaction costs and 3s transactions against 10min. the small answer.
There are lot of differences b/w Steem and Bitcoin. Both are crypto currency but runs on different blockchain. Bitcoin is the leading coin with a worth of 3850$ while steem is laging behind with a values of 0.3-04$. Steem block chain is much faster than Bitcoin in case of transaction and processing. Transaction is free in steem. Steem also provides platform like steemit, dtube, dlive, musing, busy for socializing.
In my opinion, the steem btc completely depends.
So SBD is falling less. If the bitcoin explodes the steem price will be very good. We are waiting.
