If one were to buy and hold solid avaerge coins (not a coin that kicks out and gets 10000% gain), but rather a nice steady gain like eth, Ltc etc (top 20) and starts with 10k, is it possible to reach a million without trading and buying/selling at highs and lows? If so, how long would you predict it would take? Or are most coins not going to last long term, so every 6 months would I have to rebalance with newer coins?
Without certain experience, Trading and Hodling are risky. The most acceptable method of investing at the moment is ICO. For a more successful contribution, you need to carefully analyze the project. Identify is necessary for the market side. For example, the Kelvin Blockchain project has an innovative method of encryption, transmission, storage, and security. All this is based on quantum computing. Thus becoming in demand in the future.
