There have been spectacular increases in the price of altcoins in 2021. Thus it is no surprise that the market is looking for new low-priced altcoins that could make new ?crypto millionaires.? As a result of the recent sell-off in digital currencies, cheaper altcoins might look like attractive assets due to their potential upside. Therefore, today I?ll discuss seven low-cost cryptos that still have solid upside potential in the rest of the year.

What a week it has been for cryptocurrencies. In a matter of days, many of the darlings among digital assets are about 50% down from their all-time-highs hit earlier in the year. For instance:

Bitcoin (CCC:BTC-USD) fell from $64,863 to $37,949, but still up 29% year-to-date (YTD)
Cardano (CCC:ADA-USD) fell from $2.46 to $1.55, but still up 782% YTD
Dogecoin (CCC:DOGE-USD) fell from $0.74 to $0.34, but still up 5,950% YTD
Ethereum (CCC:ETH-USD) fell from $4,362.35 to $2,591.87, but still up 255% YTD
The recent sell-off in the cryptocurrency space is the biggest in over a year. Yet, the correction across cryptos is likely to bring back interest among investors who are looking for ?penny? altcoins that could be the next Dogecoin.
