I am Jens Leinert (aka Onleines) and have spent my professional career in the internet payment industry. Today I am fully dedicated to the topic of Bitcoin as a means of payment.
With over 20 years of experience in the online payment industry, I became aware of Bitcoin and its benefits for payment processing in 2013. Since 2020, I have focused exclusively on Bitcoin and the Lightning Network.
As managing director of the Bitcoin e-commerce agency Internetactive, I run the Bitcoin directory Coinpages and the information portal Coincharge.
On my YouTube channel, I explain everything to do with Bitcoin payments, and as a board member of the Bitcoin Bundesverband, I advocate for the interests of Bitcoin companies.
I also give lecturesadvise companies on the acceptance of Bitcoin and invest in Bitcoin-only start-ups in the seed phase.
As a consultant, speaker and implementation partner, I support companies in integrating Bitcoin and Lightning as a means of payment in their online stores and business processes.
Board of the Bitcoin Bundesverband
As a board member of the Bitcoin Bundesverband, I represent the interests of Bitcoin companies in Germany. The association aims to promote understanding of Bitcoin in society and improve the framework conditions for Bitcoin as a means of payment.
My personal goal is to establish Bitcoin as a means of payment – by showing how many and which companies already accept Bitcoin and by actively working to remove legal and tax hurdles for Bitcoin payments.
Accept Bitcoin payments
Paying and accepting with Bitcoin & Lightning
How can you accept Bitcoin payments? On Coincharge.io, I provide information on how businesses and online stores can accept Bitcoin and Lightning payments – explained in a practical and understandable way.
Coinpages.io answers the question “Where can I pay with Bitcoin?” Coinpages is a Bitcoin directory for German-speaking countries with an overview of stores and online stores that accept Bitcoin and Lightning as a means of payment.
On the YouTube channel of Coincharge & Coinpages I show how to buy Bitcoin, pay with Bitcoin and Lightning and accept Bitcoin payments as a merchant.
Coinsnap offers payment modules for online stores and WordPress plugins that allow merchants and website operators to easily receive Bitcoin payments directly to their own wallet.
