I put $200 into a coinbase account (my second go at crypto) at the first "peak" of bitcoin, more or less to teach myself to not invest in hype and to monitor the hype cycle over time.

It's been very interesting to follow this over the recent peak. Coinbase probably doesn't settle each transaction immediately, since Bitcoin and several other cryptocoin transactions per second are still low, instead using internal accounting to satisfy the counterparty transaction.

Fun times. Good luck to Coinbase, they may have just triggered a run!
