Enable burn of unmoved coins

Tests

1 - Shielded pool reset - Handle reorg

Via regtest:

• Generated 101 blocks

• Used z_sendmany to shield block 1 coinbase to a z addr.

• Generated 209 blocks

• Used invalidateblock <blockhash> on blockhash of block 290

• Generated 40 blocks

• Used reconsiderblock <blockhash> on blockhash of block 290, to simulate reorg

• After reorg (to new longest chain), balance is still 0, as it should be.

• Balance also became 0 after zResetHeight without reorging (after just stepping past block 300 linearly).

OK

2 - Shielded pool reset - Handle spends from previously funded wallet.dat shielded addrs (by failing)

Via regtest:

• (revert code in wallet.cpp)

• mine to 290, generated into wallet.dat

• send block 1 reward to a new z addr (z_sendmany)

• mine 1 to confirm

• stop daemon, move wallet.dat elsewhere

• mine to 301 in a new wallet.dat

• stop daemon, replace wallet.dat with old

• try to spend matured, previously mined coins to a new z addr (z_sendmany)

• ensure that they 1) still appear, but 2) fail with joinsplit requirements not met

As expected.

@akentunal Wrong place for this type of question, but here is an answer(also answered you on reddit)

Make sure the exchange is supporting the fork, or move the coins from that exchange to an exchange that IS for sure supporting the fork.

Or you can use zelcore wallet on Android. https://play.google.com/store/apps/details?id=com.zelcash.zelcore&hl=en_US
