I started cryptocurrencies investing in 2017 right before the last bull run in this market. Buying Bitcoin at that point didn’t make a lot of sense for me. I started to invest in several altcoins or alternative currencies. Basically, these are cryptocurrencies that are not named Bitcoin.Once I started to understand the market better, I saw a lot of altcoins return 100% or more to their investors. This is my game plan going into this market.To break my investment down further, there is a possibility several altcoins could see a 1000% return. Many of these altcoins are trading for around a penny or less. To me, these altcoins have a good chance of seeing a great return on my investment.Altcoins that could see 10X returns in the next bull run. This list is what I am investing in and is not a recommendation for you to buy without doing your own research.The altcoins I am buying right now include the following:Digibyte (DGB) — currently $0.02IOST (IOST) — currently $0.006NIM (Nimiq) — currently $0.002VET (VeChain) — currently $0.01DX (DX) — currently $0.001
