The best strategy is to not make transactions when fees are high.
Best advice!
You don't pay high fees when you don't make transactions, no sarcasm here.
There is little a guy can do to avoid fees when he is faced with a full mempool.
- you should consolidate inputs, yeah...what the hell can I do now, especially since I'm doing transactions and ending with more outputs as we speak, you can consolidate them if we hit fees of 2-3 satoshi but when was the last time that happned?
- choose a day with fewer transactions, again yea...let's all stop doing transactions on Wednesday and do them on Sunday, I wonder how this will end as I have a fuzzy picture about it
- use and altcoin, but if you have BTC it means to send BTC and exchange, ups there si a flaw already
Honestly, other than paying the required 10sat/b and hope to get a place on viabtc there is no real way to avoid higher fees.
Common guys, admit, this is gold:
Another way is to fill your WebMoney or Skrill wallet
The best way is to use a centralized service.
Oh, what times we live in...
