How to choose crypt currencies? - (1) Is it available for payment?

This is just my opinion, but I think there are 3 points for choosing crypt currencies to invest in.

First of all,

"Is it available for payment, now and in the future?"

For example, I'm now interested in these currencies:

・Bitcoin
・Bitcoin Cash
・Ethereum
・NOAH
・Cardano ADA

There are more and more shops that accept BTC, but recently the transaction fees are a little bit higher. In the future, lightening network will lower the cost for transaction. Then, I expect that BTC will be convenient for micro payment.

BCH's transaction fee is cheaper than BTC's. And also, BCH's speed is faster than BTC's. Recently the size of one block has been enlarged to 32MB. I think that these features boost the price and value of BCH.

ETH is used for payment for participating in many kinds of ICO's. Of course, smart contract is the good point of ETH, but also, I think that payment speed and transaction fee of ETH are the advantage of ETH.

Noah coin is an ERC20 token, which is listed in HitBTC recently. Initially it seems that cooperation with affiliated companies is progressing as means of remittance of OFW in the Philippines as a remittance means between Japan and the Philippines. Moreover, it will be able to be used as a means of payment in cities and resorts such as Noah City and Noah resort. I think that Noah foundation that runs the projects are steadily implementing realistic projects.

Ada (ADA) is expected to increase its value in the future, such as the spread of ATM and the issuance of debit cards. It seems that development is done efficiently and systematically, and I expect that it will be better than BTC and edifice from now on.

Besides this, there may be good currency.

When the virtual currency bubble bursts, I think that this is the most important thing:

"Whether it can be used as a means of payment, how about in the future?"
