I just got some Ethereum for the first time last week. I've been using Litecoin as a means of exchange, rather than Bitcoin, for a while, since it's quicker to move and costs less to do so.
I've got Basic Attention Token in my portfolio, as well as Decentraland (my husband wanted it), Civic, Stellar Lumens, Ada, Ripple, Power Ledger, Verge, and Reddcoin. I buy, sell, and exchange among these periodically, as prices change.
The only two I haven't sold and gotten back into at a different price recently are Verge and Reddcoin, simply because I'm being stubborn about them. I feel like they will eventually do well, and I've got so many coins in each of them, I hate to move it around.
I did make a little profit on Digital Note just by holding it for a few days last month, based on a prediction I read on Steemit. I bought a bunch at six cents, and sold them a few days later at ten cents, and now it's at four or five cents, so it was a nice, short-term profit, but I don't do many of those.
Crypto is definitely interesting and exciting. I read that like 97 or 98 percent of people in crypto are men, worldwide, so it's cool to know I'm one of the few original female adopters. :)
The one we have really made big gains on is Smartcash - thankfully we were able to make a bunch on Bitcoin and them dump it and buy lots of altcoins that have gone up too.
We are mid term - 3-12 months investors on most of them, but if Smartcash becomes the new Bitcoin we are made :)
I tend to choose the coins but Deb handles the exchange stuff - that just spins me out, so geek...
