Bitcoin’s ecosystem, in addition to its exchange rate and market capitalization, had quite a tumultuous March due to escalating hostilities between proponents and developers of the 'Segregated Witness’ and ‘Emergent Consensus’ upgrade proposals.

However, the temporary instability has not dissuaded digital currency entrepreneurs from continuing to invest capital in Bitcoin ATMs (BTMs).

You'd think so, but apparently they do. Most people don't give feedback on Coinatmradar, so they will still list them even if they haven't been working for years. In Spain one of the largest providers (ATMs Bitcoin Exchange SL) has turned into a big scam. Besides not refunding when they ATMs aren't paying what they should (which is very frequently), the owner is also running several ponzies which have stopped paying. There are several threads about it in the Spanish forum. I tried to warn about it on Coinatmradar but was banned.
