I have assigned different bitcoin addresses to the users of my website to which the users can make payment to use the website. However the amounts are generally small like .0001 BTC to .0005 BTC. How can I consolidate the small bitcoin balances to a single wallet without paying transaction fees of .0001 BTC for each wallet.
There's not that much you can do besides using a centralized service where either- your customers deposit some coins to have a "prepaid" account. That service could be you.
- the service collects small amounts and has a way to get them into transactions without a fee.
Depending upon your needs, I would usually suggest the first option.
