Definitely. You have to select well which altcoin to invest on. This time is very different from the past years as there is upsurge of new alts and knowing which are worthy to invest on will be tedious yet productive as your investment will have greater chance of gain in return. So it is very important to have a thorough research on selecting an altcoin to get rid of possible loss eventually.
Some alts didn't make their values last long, especially now that the market is arent in good shape, so better choose companies that are into developing and have ideas to evolve their project for potential growth.
