When I discovered Bitcoin in 2012, I got this warm fuzzy feeling of excitement, and I just had to invest in some. And all this time since then I never bothered with altcoins since they hardly offered anything new that bitcoin couldn't do.
But then along comes the IOTA tangle system and completely blew my mind. How can you design a cryptocurrency without a blockchain? And without transaction fees? Without miners and without PoS? And to top it off completely scalable. Apparently the tangle system does away with the need for a blockchain and gives us the opportunity to transact with eachother completely free.
I think IOTA will give Bitcoin a run for it's money once it grows a bit more and is tested more unless the lightning network works as intended and will also give us practically free transactions. I'm hoping lightning network works as intended, but if not I have taken a small stake in IOTA as a hedge against Bitcoin failing.
Most of my holdings are still in Bitcoin, but I've invested some into IOTA since it is just about the only other cryptocurrency I believe in atm. Ethereum doesn't scale well and will loose in the long run I believe. All the privacy focused coins will loose to privacy features implemented in coins with more network effect. And don't even get me started on the copy cat coins and hardforks of bitcoin.
The warm fuzzy feeling is back and I'm gonna get rich with IOTA, I can feel it in my bones.
