Apparently if a problem is identified it is half solved . Coin holders needs to be carefull. But i was complaining why not their is a coin personal holder which is not dedicated to any coin. Like a personal wallet can hold any cash right. Dollars, pound...... so i need a detached device which can handle any blokchain coin which is detachable like a flash disk. And when ever you want to have a transaction you will plugin and send or recive into your personal bank devise.
Daont you think we need one of those specially i make a daily exchange to ten or so coins by observing the markets so it becomes a tiresome job to open a wallet in every vender wallet.
Anyway good luck on all steemers to be profitable in cash and in the readings of blogs. Belive me i started my exchange market after reading steems. And i make a 250,000 dollars since three monthes.
Respect.
