I think its a very risky decision. Selling hard asset for crypto is a decision which I never recommended. Bedside that your altcoins list is good to go. But I would suggest its better to hold 40-50% of your portfolio in bitcoin.
A lot of coins are like dead coins currently. There is no trading volume. Sometimes just a few dollars after some days. We can only hope that one day the trading volume is going to increase for thoses coins.
