Altcoins are also good choices when it comes to cryptocurrency investment. However, not all the altcoins are worth investing in because some have dead ideas and products which are of no demand on the market. It is very good to study the project and its coin very well before investing in them. This will reduce the risk of falling a victim to scam and unsuccessful projects.
Indeed, not all projects are good to participate in and not all coins are worthy to hold.
Even the price of alts currently are cheap, its still better to do an extensive research on what coins has potential and real use cases so it will likely to recover once the market condition is turning better.
