So if I understand correctly, even though DGN doesn't have its own wallet, keeping coins you buy in your MEW wallet will somehow get calculated? So when you go to buy in an ICO on DGN you will get special treatment?

If so, how do they even know to notify you of the pre-sale for the new ICO? They have your MEW address but not your email address.

And how do they pre-approve you for KYC off just a MEW address?

It's one thing if you bought DGN in their ICO, but for those who buy on exchange, how does this work?

Market cap matters if you're taking a "buy and hold" approach. If you are a day trader, it is true that a price under $1 is likely to see more purely speculative gains. That's because an awful lot of people think the way the OP does. So it becomes a self-fulfilling prophecy that money pours into these cheaper coins, even when their market cap is ridiculous.

For those not understanding why market cap matters for the long run, consider the current value being delivered by ETH, a platform that so many ICOs are coming out on. You have to buy ETH to buy into most of those ICOs, plus systems are running on it. That gives the coin real value.

Then consider some of these cheap coins with ridiculous coin supplies that are in the top 20 coins. Now I've bought into some myself, but I've also been trading in and out of them, taking the gains. That's because there is no way these coins are worth as much as ETH in terms of value being delivered. Yet the other day one was knocking on the door of actually passing ETH in total market cap! A coin that isn't even crypto, that is not currently in use anywhere, and that by virtue of its own purported mission has to be kept at a pretty steady price so that banks could use it for transacting.

So yeah, for a while it was 10x for even someone who bought in just a month before (me), but it can't maintain that. There is no way that coin could survive longterm at those prices because the market cap above ETH's is too absurd for the speculative bubble around its mainstream media pump not to be pierced.

Anyway, to answer your question... good day trading options under $1 are TRX, XVG, RDD
Good hold coins under $1 are SNM, LEND, and XLM.

Good luck!

And it has to be this way for what they purport to do. Now I'm not sure they're going to actually get any banks to use XRP, even if they get them to use Ripple protocol, but let's assume they do. Then they have to hold the price of XRP steady for it to serve its purpose.

What bank can transact in a currency that fluctuates in value by 20% in a given day?

That's why some of these coins hold such a huge coin supply in their own stash. Any coin used for banking transactions has got to be stable.

So apart from the thoroughly anti-crypto idea behind XRP, and the lawsuits pending against the company, it's just not a good long-term hold for price appreciation. This one is going to trade between $1-4 indefinitely. And will still be over-valued most of the time even at the top of that range!

I'm glad that I'm in both these coins. I hadn't noticed anything different with them, because everything jumped overnight since yesterday. But nice to see there are some fundamentals reasons, not just normal market fluctuations, behind it.

Well often you can profit from something you believe in or profit from something you don't believe in. I invested in XRP  for profit, but once I found out more of what it was about, I sold. Now it did go up more from where I sold, but I still made 3x in the meantime. That could have been 6x by the time it started its decline. But I just don't believe in that company or its mission (nor in the value of the coin even within what its doing). I put that money into SUB, which I've also made 3x on and where I'm committed for the longrun because I actually want to see the company achieve what it's setting out to do.

That's a great way of putting it. I think I've done the same by default without really planning it out that way, but it's a good way of planning.

I didn't actually mean for anything to be in my "trade budget" column originally. I even moved some things off the exchanges to offline wallets I should have left on the exchange to trade. I thought when I bought them they would be longterm holds, then I found out more about the companies and wanted to sell to buy something I liked more (either for profit or for mission). I paid so much in fees moving back and forth in just a couple weeks. I also missed the top of some tokens because I didn't realize I needed to buy some ETH for gas to be able to move anything from my wallet back to the exchange!

Now I don't presume something is in the "hold budget" column until I've actually held it over a month. But I still choose coins based on that. Stellar XLM is one such play. It's done all right for me on profit (3x in 1 month) but there are coins that have made me a lot more in a lot less time. For purely trading it isn't a good play, but I am committed to being a supporter of that company's mission and a part of its journey.

And then there's Tron TRX. I got in at .03 so even though it's given back a lot of its gains, it has still made me 5x even now. (At one point it was 10x.) That's the one I wanted to sell at .20 but couldn't get out of my wallet. I don't care about that company's mission at all, so am just looking for the right price points to move in and out of it.

When you choose to invest in a coin, is it always about one thing only, that you think you will profit more from spending the money on that coin than on any other you know about?

Or do you sometimes consider the mission of the company (and it's likelihood to actually deliver on that promise)?

I guess they want to make sure we aren't someone they want to kick out before they let us annoy the old-timers.
