I've got a few grand in Bitcoin. I've been doing $25 a week. My goal is $2 million. I know that's not going to happen overnight, but what do you guys think is a realistic timeline? 20 years? I'm open to investing more. How much should I be investing?

Hi eveyrone,
I'm trying to make on the some trials with ZKCP.
I'm trying on testnet using two different wallets.
So basically i used a script like the following:
OP_SHA256 <H> OP_EQUALVERIFY <seller\_pubkey> OP_CHECKSIG

From the buyer wallet i created that address and funded it (P2WSH if i correctly understood).

Now I'm trying different ways to redeem the UTXO of that address from the seller's perspective and I cannot find any way to create a transaction that does that.

Can someone help me?
Am I missing something or doing something wrong?

I'm trying everything out on a testnet.
I'll leave here the link to the address with unspent UTXO that I've created.

I'm using bitcoin core from terminal and also trying some bitcoinlibjs scripts.
