Wow...this is complex.  Kraken and coinbase have a very limited # of altcoins to trade with.  And even if I wanted to deposit my $ there it could run up charges depositing and withdrawing from my credit cards or bank account.  Brewmaster said to be careful with USBT.  Where is the danger?  Since it is an altcoin can it vary in value...is that the danger?  If so then it seems that the best thing to do would be, once I have sold the BTC, to immediately purchase another safe altcoin that will hold its value.  If I had sold an altcoin then it might be best to invest it in BTC.  With BTC it is a safe investment but still can vary in value.  Am I correct on this evaluation?  Any further advise would be helpful.
