The main problem when sending bitcoin with difference kinds of wallet are excessive Bitcoin fees, for small transaction will get difficult choose they have paid over $3 to $5 and some time could be large amount of fees have to sent.
imagine any auction
where bidding starts at $1
in any competitive bids. imagine if the auction house incremented the next bid by $5, with 10 SEPARATE bids the price hits $51
now imagine if the auction house incremented the next bid by $0.10 with 10 separate bids the price hits $2
lowering the increment bidders have to fight over allows more opportunity of priority without the fee going 50x
