A lot of depends how useful is altcoin and does it have any practical use.
Now many people have cryptocurrency and they want to spend their cryptocurrency for trips, vocations and for shoping and to receive different discounts in cryptocurrency.
unfortunately very rare we met those utility in our real life. so far i am only know StormX which i could use for having trip, paying bill on online marketplace. most of utility from crypto project used in cryptocurrency market ecosystem only and few of them could to pay our daily needs bill.
It is very important to evaluate the potential of altcoins not to lose money on investments.
Now all altcoins will be able to bring profit.
Not all altcoins will be able to survive during the fall of the market.
only altcoin with real utility in crypto ecosystem will survive for long time no matter what market condition.
