I think you should split up your money like - 50% btc, 25% ltc and 25% on eht. They are the strongest coins in nowadays and in one year you will have prifit 100%+. If you what something less popular try SNM, ADA, XLM, BNB, WAWES. Gl my friend!
I agree that it is essential and a good practice to split up and manage our trading bankroll and not just doing any all in trades for no real reasons. Proper bankroll management is one of the key to get potential good profit and at the same time preventing one from getting rect out all of the bankroll in just one awful trade.
