Bitcoin.

Bitcoin does not qualify.However, if you're looking for more passive opportunities to invest, there are a few syndications that qualify for 1031 exchange treatment, such as 721 UPREITs (Real Estate Investment Trusts) or DSTs (Delaware Statutory Trusts).

Otherwise, it's onto equities, timber, oil, Bitcoin, etc.Gary, Indiana isn't worth it. 

But, let's say the PPM says it is taking pref equity positions in real estate syndications, and you find out the sponsor is investing everything in, say, Bitcoin exchanges, then that is an issue.

Had you invested in Gold, Bitcoin, Tech, Equities, PrivateEquities, Water, Energy, you have generated a massive wealth in 25 years.

I don't plan on stopping my investments with them, same with my other investments, I'm no day trader and in it for the long haul here, I treat it like my IRA, it goes in and I'll get it back way down the road. 

It prevents wholesalers and “Re-traders” from taking your property off the market and stealing the time it’s worth the most, the first weeks it’s listed. . 

Much like I do with bitcoin when it was $5. 

And if by investing in S&P your talking about being a trader, I'd remind that >80% of people loose $, if not more.

If you day trade, sometimes the trading platform performs better than you and at times, the trader gets wealthy.
