We are creating a simple web store, where we want to be able to received Bitcoin payments. We don't want to run our own node (we don't have resources for that) and want to use some API to scan the Blockchain and detect incoming payments.

The question is: what is the most reliable API nowadays? We tried Blockchain.info, but it has some issues (we've heard).

What would be a better alternative?

I've seen this news recently: https://www.investopedia.com/news/bitcoin-tax-looms-irs-orders-coinbase-turn-over-user-data/ And now I'm worried about my tax report for the next year. I've bought 1 Bitcoins at Coinbase last February and I still hold them. Should I report this as my asset? Or should I just ignore it?
