I'm very reluctant to respond to this as I don't want to recommend something I have a position in. I saw the thread the first time it was started and since you asked again a follow-up, here goes:
My biggest cryptos position is Tezos (xtz) and you invest in Tezos
with bitcoin, rather, by trading btc to xtz
What's the value proposition?
xtz is based on liquid proof-of-stake blockchain security model which yields about 8% annual returns (if delegating to a baker aka miner) or about 9.5% if solo-baking (aka solo-mining)
What does it mean in layman's terms?
If you invest $100K in xtz today (with that amount, you should be solo-baking, but you can still delegate to a baker if you don't want to setup your own baking operations), you will get about $9.5K in yearly returns in xtz coins based on today's valuations. Just like investing in dividend-yielding, this is separate from the actual $ value rise or decline of the xtz.
For simplicity, let's say xtz is $1 each (it's trading about $1.80 currently), you will get approximately 9500 xtz in your baking wallet, or about 78 xtz per cycle (every 3 days).
If next year, May 19, 2020, xtz is trading at $2, your actual returns on your $100K investment would be significantly more, and of course if xtz is $0.5 your returns are significantly less when measured in $ value
There are other Proof-of-Stake coins, but xtz is Liquid POS, which means you can move your coins anytime and sell it anytime, unlike other coins that lock you for a specified amount of time. Be advised that moving your coins or changing delegations means you will lose the rewards for that cycle on (length of each cycle is ~ 3 days, or 4096 blocks).
The sample above is for $100K, of course only invest what you're comfortable with, so, adjust accordingly if investing $2000 or $10,000, but to be a solo-baker, you need at least 1 roll, which is 10,000 coins, or about $18K and many baking services will only accept delegations of 1000 xtz's or more
