WTF are you on about? all funds are spendable. all funds are real, no matter what date they were received
that address contains:
1 coinbase and 43 address to address transactions
a coinbase is spendable. but being a coinbase is not a transaction in my eyes. its why it was given the term 'coinbase' to separate it into a different terminology from regular transactions.
but as i said ALL the funds are spendable, all the funds are real.
i know this is digressing off the OP's question. and being pedantic, and that franky1 already knows about it, but the very first coinbase is not spendable due to a quirk in the Bitcoin code. Every coinbase after that is spendable so SmartIphone would consider the second block's coinbase as the first transaction.
However, I take the majority's view that the pizza sale was the first Bitcoin transaction.
the very first UNSPENDABLE coinbase
https://blockchain.info/address/1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNathis is part of the genesis block and yes there are reasons it is unspendable as you say. (note 1A1 address unspendable note 12c address spendable)
but other coinbases for the other 400,000+ blocks are spendable
but other transactions for the other 400,000+ blocks are spendable
the first transaction was in block 170

the first trade (known transaction for goods/services) was in block 57035
https://blockchain.info/tx/49d2adb6e476fa46d8357babf78b1b501fd39e177ac7833124b3f67b17c40c2aafter this point trades become more common and it became unknown due to no one advertising every trade, and so now we just deem a transaction and trade as the same thing and just call it a transaction.
again transaction involving 2 parties.
a coinbase does not involve 2 parties.
but this is more about "social interpretation" than anything technical
