You found a partner very quickly. I hope your quick acquaintance doesn't lead to quick disappointments.
In such matters, it's crucial to think everything through carefully and calculate all possible risks if you're investing large sums of money in this business. Preparation can usually take several months.
Same thing I was thinking he was too fast to accept someone as a partner. and just like you have said FP91G I also hope his quick acquaintance doesn't lead to quick disappointment.
I believe if he thinks everything through he may not even see the need for a partner in this mining journey he is about to begin, because like he said he already has 70 percent of what should be needed to start mining so I see no reason for a partner.
I believe he may have already started with his new found partner however OP if you are seeing this comments think very well and reconstruct your plans so you won't be disappointed at the end of everything.
