As you know the market status at this time,i want to know about what are your planning?
Because i saw many people converted their altcoins into USD at low rate and some are selling because day by day btc going down.
Converting the crypto currency to the USD is always good thing to do so that you can not loose more % on your original your investment. Thats your precautionary step but selling them at too low rate is also not advisable either! Always sell if you think investment is going to be dumped below 20% from the break even point of your investment.
However, if the selling is already done then surely you can go ahead and make investment again if the crypto falls even below that rate. That is obviously your profitable investment for the future.
