Starting with Bitcoin,
The break from the ATH took it well below 23.6% of the ATH and 2018 low, this level is 50900, however it stopped on the 47860 Major Gann square. Use 50900 as the swing point now. Any rally back above it, look for the long term target of 67700, any rally that can't get above 38.2% at 54250, will be a negative sign and with a close below the swing point look for the long term swing point of 42000, this is 38.2% back to the 2018 low, if this levels gets taken out the top could be in for awhile, just as it was when they made the 2017 high and took out 38.2%.
The last setback in Ethereum on 4/19/21 held 23.6% back to the 2018 low perfectly and that took them to a new ATH. The break from the new ATH has fallen short of 23.6%, this level is now 2045.00, as long as they remain above it look for the long term target of 2945.00. Below it look for the long term swing point of 1670.00, this is 38.2% back to the 2018 low, like Bitcoin taking out this level could mean the current top can last for years.
Litecoin has now held 38.2% back to the 2018 low for the third time this year, the first was at 122.00 on 1/11/21, the second on 2/23/21 at 160.00 and third on Friday at 215.00. As mentioned in the two other crypto's above, 38.2% is key to the long term trend, above it, look for the long term target of 370.00. Below it, look for 61.8% at 140.00.
Ripple is the weakest of the four, it has taken out 38.2% back to the 2020 low, this is 1.27 and with 38.2% back up to the high being 1.30, we will use this area (1.27/1.30) as the swing point now. A failure to get back above this area should send them to 61.8% at .81 and then 78.6% at .51. Provided they can get back above 1.30 look for the long term target of 2.10.
