Edit: Don't just downvote, tell me where I'm wrong. This same weird propaganda that running a node of 100KB/s worth of transactions is actually a problem has been going on for years.
The number of transactions you can fit in 1MB (or whatever the current limit is) is very limited. Right now the biggest challenge with cryptocurrencies is that they do not scale to large numbers of transactions per second. This had resulted in $10 transaction fees and long delays in the past. Companies like bitpay refused to process your transaction on Steam because the exchange rate has changed significantly by the time your transaction has been confirmed on the blockchain. So you ended up missing $0.5 on a $39 transaction. You can decide to transfer the missing amount and pay the $10 transaction fee again or you can get a refund and bitcoin deducts the $10 transaction fee from your refund while bitpay is sending it back. The end result? Steam stopped accepting Bitcoins and so did other companies that year. I'm sure the fees are low again because all the people who wanted to use Bitcoin for day to day transactions have left because no platform accepts bitcoin payments anymore and therefore only the speculators are left who rarely initiate transactions.
The block size for Bitcoin is 4MB, not 1MB, too.
No it's not. Segwit introduced a new concept called block weight that's larger than 1MB, and in practice with normal transactions it gives around 1.4MB.
