if its right time, whats your suggestion ?
in bitcoin? no.
since you want a long term investment then invest all of it in bitcoin. you can buy slowly not all at once. buy the dips for example.
the time is always right to buy bitcoin and hold for long term.
all the rest are good/excellent investments for short term or in other words if you are a trader. if you look at their histories, they get pumped in a month or less then it is all downhill from there. so you may buy now, they get pumped 3x and since you are holding long term they come down in next 6 months and in a year the price will be lower than what you bought again and you lose money.
