in my opinion you should spend more money to buy bitcoin. because bitcoin is the main currency, it is suitable for long-term investments and bitcoin is also a benchmark for altcoin. so the percentage for bitcoin should be 60%. the next 40% is altcoin. and in my opinion LTC also includes good coins and very potential. but everything goes back to your decision. You have done your research seriously.
Agreed! because recently bitcoin price hit 9k+ and many experts predictions says that It will reach 100k in the coming years. Yeah, I should increase my investments for bitcoin. Thanks for your valuable Suggestion.
