I've been watching Chad Carson's videos and his approach of accumulating more properties than you need, then start using that income to pay off mortgages and cull the lower performing properties makes sense to me.

As you read these books, watch the BiggerPockets podcasts.

Main questions should ask about the seller's:- Reasons/Motivations for wanting to sell- Desired timeline to close- Plan's after selling (relocation, reinvesting proceeds, 1031 exchange, etc)- Back-up plan in case they are unable to sell within the desired timeline- Reasons for not already selling to/with a investor or RealtorAdditional questions will depend on the type of seller lead i.e. pre-foreclosure, probate, fsbo, absentee owner, etc.Here is an example of a youtube search you can use to begin finding call recordings.There are 1,000s and you'll find that the best/most effective ones don't even sound like sales calls.

I don't know much about digital currency, but will watch this thread to hear thoughts from those in IT.
