Wait for a second layer or sidechain that works with bitcoin to do payments with it.
Bitcoin is a store of value that puts security before speed. That isn't changing ever.
There are second and third layer solutions being worked on (many are aware of Litecoin) that are "planned" to be used to solve the payment issue.
The altcoin/sidechain will send the payment immediately and reconcile the users bitcoin later... allowing for the security of bitcoin and the scaling of payments without screwing up bitcoin.
Thing is that using a sidechain would request to pay a fee on the bitcoin chain aswell and I dont think it's fair to pay for each single movement, which drives me to believe that it's not efficient to use the same chain for information/data storage, sort and inmutability needed and provided by bitcoin as the chain used by bitcoin which is mostly economic data storage.
For example, a project I liked from it's beginning is bitcrystals, you combine gaming and crypto economy in one thing, but I don't see a single chain (Bitcoin's) to host all that information as viable in long term future. This has been proven by ethereum.
Year's ago I read a post in this forum about researching better compression rates for everything stored on a blockchain but I don't think anything has come up.
I kinda forgot how sidechains work tho.
Do you know the adage: Show them the money!
When a customer pays using his/her Visa/Mastercard at a point of sale, the merchant is charged between 0.5% to 3% per transaction. It can even turn to be a loss for the small amount, (that's why the POS have a minimum payment like 10$/Tx). If you have an average of 1.75% per transaction this can represent a large amount of money on a company's income.
What about if a shop could increase its income by 2% per year just by using another payment means (it doesn't have to remove all others). And/or why not reducing the prices, or create jobs?
Another of Bitcoin probable increasing problem will be fees for transactions, I see bitcoin as a coin that will be used mostly by giant's to move big amounts of money and that day by day consumers will have a different option, not sure if lightning was supposed to help with that.
I guess that if bitcoin ever is adopted users will need to adopt a kind of financial identity to link with their wallets. For legal purposes hehe.
