The decision of when to buy rests on the person who is making the purchase as it would depend on a matter of factors; Someone who is buying in for the long term hodl does not bother about short term price changes and believes that in 10+ years the value is going is to much higher.
Someone who is not buying for the long term are usually more picky about when to buy and would not want to purchase when the price is on the way down. This is much more risky and would require some technical analysis and some luck as well.
I was thinking about long term. Thanks for response.
My advice for coin was just given in a different thread.
...
My suggestion is hope for a crash and buy some coins.
BTW we are down to 38900k
so buy 100 usd worth and then hold 300 in cash.
If we drop to 35 k buy 150 usd worth and hold 150 cash.
If we drop to 30k buy 75 usd worth
If we drop to 25k buy 75 usd worth.
hodl all of the coin above for 4 years no matter what happens.
Then thank me.
worst case is you only buy 100 worth at 38900 and it moons.
best case you get to buy all this levels you hold for 4 years and it moons.
I am anti ETH in general
So My advice it to do something like above.
25% of your money today on BTC hodl it for 4 years
75% save for more drops.
say
35k
30k
25k
or
34k
27k
20k
I would stay away from ETH
but
if you insist
do this
20% on BTC 5% on Eth today hold no mater what for four years
save 75% of your money for more drops
20% BTC 5% Eth. say at 35k and 2500
20% BTC 5% Eth say at 29k and 1900
20% BTC 5% Eth say at 23k and 1400
or
33k and 2400
26k and 1700
19k and 1000
good luck
