I need advice on alternative currencies to purchase before btc rallies above 8000 usd.. anything among the top 100 coins on coinmarketcap will so just fine
Since you are asking for crypto that is already among the top 100 coins then why not go with,
ETH, DASH ,LTC ,and stellar this is the great crypto to invest for me but you should do your own research before investing and take our words as a suggestion you should decide for your own.
Do a research about the coin though there are many suggestions, you have to decide which is the better. Most of potential altcoins are those that exist for a long run. Though the price is unpredictable, it always get the rise from the cheap price, just wait for the good time to gain profit.
